A+B=105, A banding B = 8 banding 7, B - A =

A + B = 105
A : B = 8 : 7
B - A =???

A + B = 105
8x + 7x = 105
15x = 105
x = 7
MAKA
A = 8(7) = 56 DAN B = 7(7) = 49

B - A = 49 - 56 = -7

#SEMOGA MEMBANTU

A+B=105 , A:B=8:7 ,jumlah prbndingan =8+7=15
A=8/15 × 105
=8×7=56
B=7/15 × 105
=7×7=49
Maka,A-B = 56-49=7
