Question

find 87.5%of 640 give some answers​

Answer 1

Answer:

640/x=100/87.5

(640/x)*x=(100/87.5)*x - we multiply both sides of the equation by x

640=1.14285714286*x - we divide both sides of the equation by (1.14285714286) to get x

640/1.14285714286=x

560=x

x=560

now we have:

87.5% of 640=560
