Answer 1

Answer:

1. Option A
2. Option D

Solution:

• In order to multiply fractions, we should multiply the numerator of the first fraction times the numerator of the second fraction, like so:
• 3•5=15
• Do the same with the denominator:
• 10•7=70
• 15/70 is the answer.
• Same with the other fractions:
• 7•2=14
• 10•4=40
• Hence, 14/40 is the answer.

Answer 2

Let's start off with  1. 3/10 * 5/7

3/10×5/7=?

For fraction multiplication, multiply the numerators and then multiply the denominators to get

(3×5) / (10×7) = 15 / 70

This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 15 and 70 using

GCF(15,70) = 5

(15÷5)/ (70÷5)=3/14

Therefore:

3/10×57=3/14

Now, #2. 7/10 * 2/4- We do the same process.

7/10×2/4=?

For fraction multiplication, multiply the numerators and then multiply the denominators to get

(7×2) / (10×4)=1440

This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 14 and 40 using

GCF(14,40) = 2

(14÷2) / (40÷2) = 7/20

Therefore:

7/10×2/4=7/20
