4/12 is bigger (than 2 over 12. It is not the biggest, but that was not the question.
5/4 is bigger. 5/4 = 1.25 7/12 = .583
You must think a little first: Which is bigger.... 14 over 16 Or 12 over 16?
4/9 is bigger.
Bigger.
Yes. 7/9=0.7777777... and 3/4=0.75Therefore, 7 over 9 is bigger than 3 over 4.
4/15 = 20/75 7/25 = 21/75 So, 7/25 is bigger.
Yes.
Yes.
1/4 = 0.25 7/15 = 0.47 Since 0.25 < 0.47, no, 1/4 is not bigger than 7/15.
(-7/12) / (-3/4) = (7/12) / (3/4) = (7/12) * (4/3) = (7/3)*(1/3) = 7/9
-3/4 + -7/12 = (-3×3)/(4×3) + -7/12 = -9/12 + -7/12 = (-9 + -7)/12 = -16/12 = (-4×4)/(3×4) = -4/3 = -1 1/3.
