Answer :
3/10 multiply with 8 on both numerator and denominator
therefore, 3/10 = 3x8/10x8 = 24/80
therefore, 3/10 = 3x8/10x8 = 24/80
I think the answer is 24/80 because you have multiplied the denominator by 8 to get to ?/80 from 3/10. Therefore, you need to multiply 3 by 8 also, which when you do, you get 24/80
