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
