Answer:
Step-by-step explanation:
500(x - 3) =5000
x - 3 = 5000/500
x - 3 = 10
x = 10 + 3
x = 13
Fraction of girls = 1 - 3/7 = 4/7
4/7 is equivalent to 72 girls
1/7 .. .. ............. 72 / 4 = 18
Total number of children = 7/7 = 18*7 = 126 Answer
For this one a simple way that you can think of it is that 1 pound of banana is equivalent to 100, 3/4 pounds of banana is 75, 1/2 pounds of banana is 50, etc.
3 1/2 pounds of banana = 350
3/4 pounds of banana = 75
If i want to find out how many loafs of banana bread I can make if ONE loaf requires 3/4 pounds of banana, and i have 3 1/2 pounds of banana then I divide:
350 / 75 = 4.66
So, with 3 1/2 pounds of bananas you can successfully create 4 loafs of banana bread. the remaining .66 is not enough banana to make another loaf.
Just put down no solution. It's unsolvable.
