7 * 3 = 21
/ / /
9 * 5 = 45
21/45 <------your answer if simplification is not required
AKA, devide both by the Lowest Common Denominator
which would be three to get:
7/15 <----- you answer if simplification is required

7/9 * 3/5 you multiply the numerator which would be 21 and the you multiply the denomanator which would be 45. So that would equal 21/45.

Since its 7 over 9 times 3 over 5
it'll be
7 3
_ X _
9 5
you can simplify 9 and 3 to:
7 1
_ X _
3 5
from there, just multiply straight through 7 times 1 and 3 times 5:
7x1
___
3x5
EQUALS
7

Someone wasn't paying attention in math class....
PS
Why not just ask your mom, teacher, call your friend, or better yet use your math book???
Why ask people on the internet to explain it to you?
