% = 1/100

so...

550 x 120% = 550 x 120/100

= 550 x 6/5

= 110 x 6

= 660

1.2 converted as a decimal (120 divide by 550)

1.2 times 550=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

If this is a calculator question the easiest hack to find any percentage of anything on a calculator is to locate the % button, on my calculator its found by pressing 'shift' then 'ans' , yours may be different but it will be in yellow above one of the buttons meaning you will need to press shift before it.

In maths whenever you see the word 'of' you need to multiply.

So 120% of 550 means 120% x 550

using my calculator i would type :

120 'shift' 'ans' x 550 =

then my answer would be 660

100% of 550 = 550

10% of 550 =55

10% of 550 = 55

120% of 550 =550 + 55+ 55 = 660

- write down the percentage as a fraction which would be 120/100
- Then we would do 120/100 of 550
- which we know is the same as multiplying it
- then we will do 120/100 times 550
- Therefore which the answer will be 660
- Is using a calculator you simply enter 120 divided by 100 times by 550 which will also give you the same answer

The best way figure out a problem like this is to break it down step by step. Lets begin by working out what 10% of 550 is. So in order to do that we can divide 550 by 10 which is 55. Once we have this we need to figure out how to get to 120%. So what we can do is check how do we get from 10 -> 120. We multiply by 12! So now you do the same thing to 55, we multiply by 12. So the answer would be (55x12) = 660

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

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.

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

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.

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!

First write 120% as 120/100 , then multiply by 550 (120/100)*550 =660 . easy

(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
