Which shows the correct way to use the rule “multiply by the reciprocal” for the expression below?
5 divided by 5/1 2 Over 9/2
5 Over 1 EndFraction times StartFraction 9 Over 2 EndFraction = StartFraction 45 Over 2 EndFraction
StartFraction 5 Over 1 EndFraction times StartFraction 2 Over 9 EndFraction = StartFraction 10 Over 9 EndFraction
StartFraction 1 Over 5 EndFraction times StartFraction 9 Over 2 EndFraction = StartFraction 9 Over 10 EndFraction
StartFraction 1 Over 5 EndFraction times StartFraction 2 Over 9 EndFraction = StartFraction 2 Over 45 EndFraction
The correct way to use the rule "multiply by the reciprocal" for the expression "5 divided by 5/1 2 Over 9/2" is:
StartFraction 5 Over 1 EndFraction times StartFraction 2 Over 9 EndFraction = StartFraction 10 Over 9 EndFraction
To use the rule "multiply by the reciprocal," you need to multiply the first fraction by the reciprocal of the second fraction. In this case, the expression is:
5 divided by 5/1
To find the reciprocal of a fraction, you flip it upside down. So the reciprocal of 5/1 is 1/5.
Now, you can multiply the first fraction by the reciprocal:
(5/1) * (1/5) = 5/5
Simplifying this further, since 5/5 is equal to 1, the correct way to use the rule "multiply by the reciprocal" for the given expression is:
StartFraction 5 Over 1 EndFraction times StartFraction 1 Over 5 EndFraction = StartFraction 1 Over 1 EndFraction
