Question

Find 0.15% of 43 cookies

Answer 1

43*0.0015=0.0645
0.0645 is 0.15% of 43

Answer 2

43/x=100/0.15
(43/x)*x=(100/0.15)*x - we multiply both sides of the equation by x
43=666.666666667*x - we divide both sides of the equation by (666.666666667) to get x
43/666.666666667=x
0.0645=x
x=0.0645

now we have:
0.15% of 43=0.0645
