Question 6 Part A:

4 x 1/2 =

Question 4 Part A:



1/4 ÷ 2 =





































Question 7:
A pitcher of orange juice is 2/3 full. If four students equally share the juice, what fraction of the full pitcher does each student get?
Answer:

2 x 1 = 2

3 x 4 = 12

= 2/12

Each student gets 2/12 of the ful pitcher.







Part 2
Fraction x Fraction
3/4 x 7/8 =

Solution: Numerator x Numerator and Denominator x Denominator.
3 x 4 = 21
7 x 8 = 32

Answer:
3/4 x 7/8 = 21/32

Mixed x Fraction
1 1/5 x 2/5 =

Solution: Convert mixed into improper. Then Numerator x Numerator and Denominator x Denominator.
(1x5)+1 = 6/5

(Whole x Denominator)+ Numerator = New Fraction

Answer:
6/5 x 2/5 = 12/25

Mixed x Mixed
5 1/3 x 3 1/3 =

Solution: Covert Mixed fractions to improper. Then Numerator x Numerator and Denominator x Denominator. Then convert answer to mixed with remainder over denominator.

(5x3)+1 = 16/3
(3x3)+1 = 10/3

Answer:
16/3 x 10/3 = 160/9
160 / 9 = 17 7/9

Part 3
Explain how to answer
1 1/2 ÷ 3/4 =
3/4 ÷ 1/2 =

If the denominator is not the same then you must find a common denominator.
Next you draw a box out of the denominator. Ex 1/4 you would draw a box divided in 4ths.
Now count up by the numerator until you can't count anymore. Ex 1/4 count up by 1.
With the left over make it a fraction with the numerator as a denominator.

1 1/2 ÷ 3/4 = 2
3/4 ÷ 1/2 = 1 1/2

Sorry theres no picture but everytime I put one something wierd happened.

What we have to do for our growing post:

Fraction Growing Post
Label it Fraction, Growing Post, User Name
a) Post your recorded quiz.

b) Using one question from questions 6 or 7 on page 202 of the textbook, explain two ways to multiply a fraction by a whole number. You should use pictures to help explain.

c) Using one question from questions 4 or 5 on page 208 of the textbook, explain how to divide a fraction by a whole number. You should use pictures.

d) Pick one word problem from questions 6-12 on page 208 of the textbook.

a) My recorded quiz


b) One question from #6 on page 202

c) One question from #4 on page 208

d) word problem from page 208 #7

Thanks for viewing my post. Sorry If I made any mistakes with my explanations. and sorry about my quiz too..

________________________________________________________________

Fraction Growing Post Part 2

________________________________

The second part of your fraction growing post is to show your understanding of multiplying fractions. Use your test to choose 3 questions.

1. fraction x fraction
2. fraction x mixed number
3. mixed number x mixed number

It is up to you how to show your understanding. You can type everything, create an image in paint or use the class ustream account. This is due by Monday April 12.

Yes there will be a part 3. DO NOT CREATE A NEW POST edit your old fraction post and add part 2 to it.
Be sure to label your post fractions and growingpost.

You also have to complete your e-portfolios and movie projects..... lots of homework. Have a great weekend.

PART 3

Just click on the link to see.. It wont upload here and the embed thingy wont work..

RECTANGULAR PRISM
TOP;FRONT;SIDE

Area =LxW Area=LxW Area=LxW
Area = 5x8 Area=8x8 Area=8x8 Area =40cm2 Area=64cm2 Area=64cm2

TSA= TOP + TOP + FRONT + FRONT + SIDE + SIDE
= 40+40+64+64+64+64
= 208 cm2



























TRIANGULAR PRISM

a = b x h ÷ 2

a = 10 x 12 ÷ 2

a = 60cm²

a = l x w

a = 10 x 4

a = 40cm²

a= l x w

a = 10 x 4

a = 40cm²

a= l x w

a= 10x 12

a = 60cm²

TSA

= (triangle)+(triangle)+(rectangle)+(rectangle)+(rectangle)
= 60+60+60+40+40

= 260cm²

Cylinder
Radius:

r = d ÷ 2

r = 12 ÷ 2

r = 6cm²

Formula:

sa = 2 x (pi x r²) + (pi x d x h)

sa = 2 x 3.14 x 6 x 6 + 3.14 x 6 x 12

sa = 226.08+ 226.08

sa = 452.16 cm²

Rectangular prism

Cylinder

formula 2x3.14xrxrx3.14xdxh 2x3.14x3x3x3.14x6x10=10648.40

Triangular Prism

If you want to find the surface area of a triangular prism you need to find the the area of the 2 triangles and the3 squares then add all the surface area of the 2 triangles and 3 squares then you should get the total surface area.

Surface Area Growing Post , JerickR873

Ok this is my growing post for math , i will be showing yo what a rectangular prism , triangular prism , and a cylinder looks like and nets , also how to solve for Total Surface Area (TSA)

1st the Rectangular Prism

the formula for the rectangular prism is:
l x w = a

one way to find TSA for a rectangle is to find the area of the side , front , and top then you just times those by two because of their opposite side

Top

l x w = a
20 x 2 =a
40x2=ax2
80=ax2

Side
l x w = a
20 x 2 = a
40 x 2 = ax2
80 = a x 2

Front

l x w = a
20 x 20 = a
400 x 2 = a x2
800 = a x2

TSA = 800+80+80
TSA= 960 cm2

2nd is the Triangular Prism

Formula
b x h = a
l x w = a
I like to find all sides just like the rectangular prism and add up all the sides

Front
b x h = a
12 x 12 = a
144 x 2=a
288 = a x2

Bottom
l x w = a
12 x 5 = a
60 = a

Back
l x w = a
12 x 5 = a
60 = a

Top
l x w = a
1o x 5 = a
50 = a

TSA= 50 +60 + 60 + 288
TSA= 458 cm2

3rd the Cylinder

Formulas
d divided by 2 = r
pi R 2 = a
pi D = c
l x w = a

For cylinders , you need to find the area and circumference of a circle and times that by 2 , for the other end , and then for the rectangle its the circumference of the circle that is the width of the rectangle

pi D = C
3.14 x 15 = c
47.1 = c

d/2 = r
15/2=r
7.5= r

pi R 2 = a
3.14 x 7.5(2) = a
3.14 x 56.26 = a
176.67 x 2 = a
353.34= a

l x w = a
20 x 47.1 = a
942=a

942 + 353.54 =1295.34 cm2
