7 out of 50 is the same as 7/50

First, change the fraction into a decimal by dividing.

7 / 50 = 0.14

Second, change the decimal into a percentage by multiplying by 100%.

0.14 * 100% = 14%

18 out of 20 is the same as 18/20

First, change the fraction into a decimal by dividing.

18 / 20 = 0.9

Second, change the decimal into a percentage by multiplying by 100%.

Step-by-step explanation: To write a fraction as a percent, first remember that a percent is a ratio of a number to 100.

So to write 7/50 as a percent, we need to find a fraction equivalent to 7/50 that has a 100 in the denominator.

We can do this by setting up a proportion.

So we have [tex]\frac{7}{50} = \frac{n}{100}[/tex].

Now, we can use cross-products to find the missing value.

So we have (7)(100) which is 700 is equal to (50)(n) or 50n.

So we have 700 = 50n.

Next, dividing both side of the equation by 50, we have 14 = n.

So 7/50 is equal to 14/100 or 14%.

To write 18/20 as a percent, we need to find a fraction equivalent to 18/20 that has a 100 in the denominator.

We can do this by setting up a proportion.

So we have [tex]\frac{18}{20} = \frac{n}{100}[/tex].

Now, we can use cross-products to find the missing value.

So we have (18)(100) which is 1,800 is equal to (20)(n) or 20n.

So we have 1,800 = 20n.

Next, dividing both sides of the equation by 20, we have 90 = n.

So 18/20 is equal to 90/100 or 90%.
