Answer 10

what bout negatives -12/20 *42/72

Answer 11

sorry 12/30

Answer 12

i mean -12/30*-42/72 how do you multiply the negative fractions

Answer 13

-12/30*-42/72 = (-12*-42)/(30*72) = 504/2160 = 7/30


So -12/30*-42/72 = 7/30

Answer 14

so to find simplest form where do you start. I mean 9 and go backwards. in other words how did u arrive at 7 for numerator

Answer 15

I divided both numerator and denominator of 504/2160 by 72 (which is the GCF of the two numbers) to get 7/30
