Question

I need to know how to cross simplify.

Answer 1

Explanation:

Okay, set them up

2 8

----------

4 10

You look at the 2 and the 10, can 10 be divided by 2 evenly? Yes so how many 2s are in ten? The 2 becomes a 1 because 2 divided by 2 = 1

and the 10 becomes a 5 because 10/2 = 5

Then look at the 4 and the 8. Can 8 and 4 be divided by 4? Yes, how many 4s in 4? How many 4s in 8? so the 4 becomes a 1 and the 8 becomes a 2.

New problem

1/1 x 2/5 = 2/5

Answer 2

Explanation:

Simplify the fractions. Write the simplified numerator and denominator above and below the old ones. Before you multiply, you can write another equivalent, simpler fraction in the place of a fraction.
