Question

Pam bought 50 kg of sugar. She used 10 kg of sugar. What percentage of sugar was left? (step by step answer would be appreciated)

Answer 1

80%

Explanation:

50 x 50 would be 100 and 50kg=100% and 10 x 2 = 20 so you used 20% therefore you have 80% left.

Answer 2

80% of sugar left.

Explanation:

If we start of with 50 kg of sugar and we take away 10 kg of sugar, we are left with
`50-10=40` kg of sugar.

To find the percentage of sugar left, we divide the decreased number by the original number.

`(40)/(50) = (4)/(5) = 0.8`

If we have a decimal and want to convert it to a percentage, we multiply it by 100.

`0.8\cdot100=80`

So, 80% of the sugar is left.

Hope this helped!
