40 is 160 percent of what number?
nadya68 [22]

Answer:

25 is the answer

Explanation:

Step by step solution for calculating 40 is 160 percent of what number

We already have our first value 40 and the second value 160. Let's assume the unknown value is Y which answer we will find out.

As we have all the required values we need, Now we can put them in a simple mathematical formula as below:

STEP 140 = 160% × Y

STEP 240 =

160

100

× Y

Multiplying both sides by 100 and dividing both sides of the equation by 160 we will arrive at:

STEP 3Y = 40 ×

100

160

STEP 4Y = 40 × 100 ÷ 160

STEP 5Y = 25

Finally, we have found the value of Y which is 25 and that is our answer.

You can easily calculate 40 is 160 percent of what number by using any regular calculator, simply enter 40 × 100 ÷ 160 and you will get your answer which is 25

got this from Percent Calculator
