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)

80% of sugar left.

Step-by-step explanation:

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

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

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

So, 80% of the sugar is left.

Hope this helped!
