Question

Rewrite 9/10 and then 23/25 so they have a common denominator. Then use > or < or = . Can someone please help. I really need help with this one :(

Answer 1

the LCM of 10 and 25 is 50

notice how if we lay out the multiples of 10 and 25, we get

10: 10, 20, 30, 40, 50, 60, 70, etc
25: 25, 50, 75, 100, etc

Answer 2

do you see how I got 50?

Answer 3

(9/10)*(5/5)= 45/50
(23/25)*(2/2)= 46/50
9/10<23/25
