Question

42 feet is 50% of what length

Answer 1

42 feet is 50% of 84 feet because 50% is half. and 42 x 2 = 84.


answer: 84 feet

Answer 2

So basically 100% is a whole.

50% would therefore be a half because 50/100 = 1/2.

So therefore we know that 42 feet is equal to 1/2.

42 = $\frac{1}{2}$

And now we just find what to multiply 1/2 by to get 100%.

1 / (1/2) = 2

So basically, multiply the whole equation by 2.

42 = 1/2
42 * 2 = 1/2 * 2

84 = 100%

So 42 feet is 50% of 84 feet.
