The price of a necklace was increased by 20% to £186.
What was the price before the increase?

£148.8

Step-by-step explanation:

The necklace is £186 after the price was increased by 20%

20% of £186 is £37.2. We know this because 20% goes into 100% 5 times, so if we divide £186 by 5, we will find out what the 20% is £186 ÷ 5 = £37.2

£186 - 20% = p

£186 - £37.2 = p

£148.8 = p

The price of the necklace before the increase is £148.8

I hope that this helps :)

step-by-step explanation:

there are 36 inches in a yard

25 : 36 = 0.69 yards (you can round to 0.70)

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100
