To find your answer, one way to do it is by cross canceling. To do this, simply cross cancel any numbers that can go into each other when divided. For instance, in, 4/10 • 5/7 , 5 can go into 10, so it would change to 4/2 • 1/7 After doing this, change 4/2 to 2 then multiply your news numbers to get 2• 1/7= 2/7 _____________________________________ Another way is by justing multiply straight across to get 20/70, so all you need to do is simply, or divide the numerator and the denominator by 10 to get 2/7
I hope this helped, and if it did, I would love if you could give me brainiest!
