Eric.P's Fraction Growing Post

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.

Hi Eric. Good job with both your video and growing post. You eplained everything nicely. And your pictures were pretty neat too. But for the last question, I think you could've explained it better. It was really good though. And accurate. But made diagrams would help. Keep up the good work!
