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

Lucinda has 9 ounces of flour. A batch of cupcakes requires 1/3 ounce of flour. A batch of muffins requires 1/4 ounce of flour.
NeX [460]

Answer:

9 more muffins

Explanation:

Lucinda has 9 ounces of flour.

To make a cupcake she requires 1/3 ounce of flour, therefore the number of cupcakes she can make from 9 ounces of flour can be given by:

(1/3)x = 9 where x is the number of cupcakes.

Therefore, x = 9 × 3 = 27 cupcakes

To make a muffin she requires 1/4 ounce of flour, therefore the number of muffins she can make from 9 ounces of flour can be given by:

(1/4)y = 9 where y is the number of muffins.

Therefore, y = 9 × 4 = 36 muffins

The number of more muffins she can make more than cupcakes from her flour = 36 - 27 = 9 more muffins
