Question

I'm stuck on this question

Answer 1

You appear to have made an odd, albeit common arithmetical mistake: you seem to have done width x 1/length instead of width x length. The correct way to do this is:

5/12 x 5/6 = (5x5)/(12x6) = 25/72

Answer 2

It's easy. Just multiply the fractions.The numerator multiply the numerator and the denominator multiply it by the denominator.
the answer is 25/72,
it means D)
Good luck)
