Answer 1

Answer: A) 15/70

=======================================================

Explanation:

We multiply the numbers across the top (numerator) to get 3*5 = 15

Then across the bottom (denominator), we multiply the values to get 10*7 = 70

So we get $\frac{3}{10}\times\frac{5}{7} = \frac{3\times 5}{10\times7} = \frac{15}{70}$

That's how we end up with 15/70

------------------------------

Extra info:

Note how 15 and 70 have the GCF 5, so we can divide both values by 5

• 15/5 = 3
• 70/5 = 14

This means 15/70 reduces to 3/14; however, your teacher has decided not to reduce (since 3/14 is not one of the answers). So that means we should stick with 15/70 instead.

Answer 2

Answer:

15/70, first option

Step-by-step explanation:

if you multiply the numerators and denomenators together, you get 15/70. you're able to reduce this, but it looks like the answer doesn't want you to reduce it :)
