Mandy and Tamara are disagreeing over the problem 4/5 x 1/2. Did I do this problem right.

Question

Mandy says that to multiply fractions, you have to multiply the numerators and then multiply the denominators. Tamara says that since there are four pieces in ⁴/₅, the answer is half of them: ²/₅.

 

1. Who is correct, Mandy, Tamara, or both of the girls? Show work to support your answer.

 

So for my answer when I did ⁴/₅ x ¹/_² I got an answer of ¹³/₁₀= 1 ³/₁₀ . So neither of them are correct. DID I DO THAT PART RIGHT?

 

2. Will Mandy's Method work for Mixed numbers? why or why not? Use the example 1 ³/₄ x ²/3  in your explanation.

 

(IM NOT SURE ABOUT THIS PROBLEM)

 

 

PLEASE HELP ME!!

Answer 1

The answer is 2/5 same as 0.4

Answer 2

(4/5)(1/2)

4/10

2/5

 

Mixed number should be converted to improper fractions to be multiplied.
