Here is your first answer: First find the multiple which is 24 12*2=24 and 8*3=24 (denominator is 24) 5*2=10 and 1*3=3 then subtract 10-3=7 Then subtract the whole numbers 15-11=4 Your first answer is 4 7/24 or A. Here is your second answer: First find the multiple which is 80 8*10=80 and 10*8=80 (denominator is 80) 5*10=50 and 3*8=24 then subtract 50-24=26 26/2=13 and 80/2=40 Your answer is 13/40 or A
