5 ft is ____ % of 37 1 2 ft; 37 1 2 ft is ____ % of 5 ft

hichkok12 [17]

Answer:

The answer is:

5 ft is 13.33% of 37 1/2 ft; 37 1/2 ft is 750% of 5 ft.

Step-by-step explanation:

Given:

5 ft is ____ % of 37 1 2 ft.

Now, to find the __ :

Let __ be $x.$

So, 5 ft is $x\%$ of 37 1/2

$5=x\% of 37\frac{1}{2}$

⇒ $5=\frac{x}{100} \times \frac{75}{2}$

⇒ $5=\frac{75x}{200}$

Multiplying both sides by 200 we get:

⇒ $1000=75x$

Dividing both sides by 75 we get:

⇒ $13.33=x$

⇒ $x=13.33\%.$

Now, 37 1/2 ft is $x$ % of 5 ft.

$\frac{75}{2} =x\%\ of\ 5$

$\frac{75}{2}=\frac{x}{100}\times 5$

$\frac{75}{2} =\frac{5x}{100}$

Multiplying both sides by 100 we get:

$\frac{7500}{2} =5x$

Dividing both sides by 5 we get:

$750=x$

$x=750\%$

Therefore, the answer is 5 ft is 13.33% of 37 1/2 ft; 37 1/2 ft is 750% of 5 ft.
