Question

Mama imparte celor trei copii suma de 960 lei astfel :Ion 3/12, Mihai 4/24, iar Matei ii da jumatate din suma ramasa. Îi raman bani mamei? Cati? VA rog am nevoie repede

Answer 1

i+m+M=960
i=3/12din 960
m=4/24din 960
M=rest:2
i=3/12=1/4
i=960:4=240
m=4/24=1/6
m=960:6=160
i+m=240+160=400
960-400=560(rest)
560:2=280(matei)
960-680=280(i a ramas mamei)
