Question

8. Peter put 4/5 cup of chocolate

Chips into cookies batter. Samantha put 7/8 cup into hers. Whose batter contains more chips? How do you know?

Answer 1

Answer: Samantha

Explanation:

Two ways you could solve this percents or fractions.

Percents

Peter: 4/5 = 80%

Samantha: 7/8 = 87.5%

Fractions

Set the denominator equal to each other

the common denominator would be a multiples to both 5 and 8 which is 40.

Peter: 4/5 = 32/40 because 5 times 8 is 40 and what you do to the denominator you do to the numerator so 4 times 8 is 32.

Samantha: 7/8 = 35/40 because 8 x 5 = 40 and 7 x 5 = 35.

Then compare and 35/40 is greater so Samantha.
