4/7 of a group of children are boys. If there are 18 more boys than girls, how many children are there altogether?

  • Math 5th -

    No of Girls
    X x 4/7=18
    (X x 4/7)/(4/7)=18(4/7)
    X=(18x7)/4 reciprocal

    Total No of Children
    18+14=32 Children

    4/7= Boys, 3/7= Girls there are 1/7 more boys than girls. There are 18 more boys than girls.
    72 boys + 54 girls = 126 total kids
