Question

Which equation can be used to solve the problem?

180 is 40 percent of what number?
StartFraction 40 times 4.5 Over 100 times 4.5 EndFraction = StartFraction 180 Over 450 EndFraction
StartFraction 180 times 0.4 Over 100 times 0.4 EndFraction = StartFraction 72 Over 40 EndFraction
StartFraction 40 times 1 Over 180 times 1 EndFraction = StartFraction 40 Over 180 EndFraction
StartFraction 100 times 4.5 Over 40 times 4.5 EndFraction = StartFraction 450 Over 180 EndFraction
