How do You Get the answer to 5/8*12/25 by doing cross multiplacation

You don't cross-multiply when you're multiplying fractions.

Multiplying fractions is really simple:

- - The numerator of the product is the product of the two numerators.

The two numerators are 5 and 12, so the numerator of the product is 60.

- - The denominator of the product is the product of the two denominators.

The two denominators are 8 and 25, so the new denominator is 200.

The new fraction is 60/200.

You could simplify it, and then it would look like 3/10.

For cross multiplication, you divide by a number divisible by the number and the number angled across from it. 5 and 25 are both divisible by 5 so you divide both numbers by 5. 5=1 and 25=5. Which temporary makes it 1/8 and 12/5. Since both 8 and 12 are divisible by 4, divide both of them by 4., 8 by 2 times and 12 by 3 times (8=2 and 12=3) So the result is 1/2*3/5 which is 3/10.
