To find 120% of 550 you would need to multiply 550 by 120 and then divide it by 100 (550*120/100) which is the same as directly multiplying 550 by 1.2 as 120 divided by 100 is equal to 1.2 (550*1.2).

% = 1/100

so...

550 x 120% = 550 x 120/100

= 550 x 6/5

= 110 x 6

= 660

1.2 x 550 = 660

A percentage can always be transformed to a decimal by dividing by 100

therefore 120% / 100 = 1.2

To find a percentage of a number you can always multiply the decimal version of that percentage by the number

so 1.2 x 550


EQUIVALENTLY


x 550 = 660

A percentage can always be transformed into a fraction by dividing by 100

therefore 120% / 100 = 12/10 = 6/5 (by diving top and bottom by 2)

To find a percentage of a number you can always multiply the fraction version of that percentage by the number over 1

so 6/5 x 550/1= (6 x 550) / (5 x 1) = 3,300 / 5 = 660

Step 1: find 1% of the number by dividing it by 100

550 ÷ 100 = 5.5

Step 2: multiply by the percentage you want to find

5.5 x 120 = 660

1.2 converted as a decimal (120 divide by 550)

1.2 times 550=660

100% of £550 is £550

20% of £550 is equal to £550 divide by 5 as 20 is 100 divided by 5.

£550 divided by 5 is £110

120% would be those values added together so £550 + £110

Therefore 120% of £550 would be £660

Working out 120% of 150

  1. Write 120% as 120/100
  2. Then since finding the fraction of a number is the same as multiplying the fraction with the number we have so calculate 120/100 x 150 = 180

The easiest way is to find 10% and then times that by 12 to get 120%.

By adding 20% of 550 to 550. So 20% 0f 550 is 110 therefore, 120% 0f 550 equal 110 + 550 = 660

(10%) (20%)

550 * 0.1 = 55 * 2 = 110


Take base number (550) find out what 10% is and then times that by two


550 + 110 = 660


Finally add the two numbers together

Hi Felicity, there are many ways to go about this question. Personally, what helped me understand all the methods to completing this question is through this: First, take 550 and break it into 100 parts by dividing it by 100, which gives you 1% of 550. Then, since you want 120 parts or 120% of 550, you multiply your previous answer by 120.


It can be written out like this: 120% of 550 = 550/100 x 120

= 5.5 x 120

= 660


Hope this was helpful!

This is a basic % calculation math, and the first thing to not here is % means a 100 of whatever you have. So it can be solved as dividing 550 by a 100, then multiplying it by 120. Or by dividing 120 by a 100, then multiplying it by 550. The result gotten from any of the two methods would be same = 660.

First of all we want to find what 10% of 550 is. We do this by dividing 550 by 10. 550/10=55

Then because 120/10= 12 we know that 12* 10% of 550 = 120% of 550

12*55=660

120% of 550 is 660

Hal Mcnulty Best Answer!

Turn the percentage number into a decimal by dividing it by a hundred, and then multiply that by the number. So 120 divided by 100 turns into 1.2, and 1.2 times 550 is 660.
