Question

Find 5% of £380
find 15% of £380

Answer 1

Greetings!

When trying to find the percentage, simply use this equation:

(Initial price x
`(percentage)/(100)`)

Where the initial price is the total amount, and the percentage is how much the percentage is. Simply plug the numbers in the question into this equation:

(380 x (
`(5)/(100)`)

= 380 x 0.05 = 19

So 5% of $380 = 19

As 15% is simply 3 times more than 5:

15 ÷ 5 = 3

You can simply multiply 19 by 3 to find 15%!

19 x 3 = 57

So 15% of $380 = $57

Hope this helps!
