Question

92/100 reduced to a fraction in lowest form

Answer 1

23/25

Answer 2

Do you need help learning how?
Do you know how to make a factorial tree of both numbers? Then you can cancel out the common factors, and add up what's left in the N and the D (as in N/D).

Another way is to find the biggest number that will divide into both, and divide it out of both. Then try again to see if you can do it again. When you run out, you're done!
