Question

Calculate. a) 130% of 220​

Answer 1

Start off by saying:
130/100 * 220
so, the answer would be 286

this is as you simplify the fraction first by 10: 13/10 * 220
then you take out the ten on each side: 13 * 22

Answer 2

Convert 130% to a decimal which is 1.3
then it’s simple math from there. multiply 220(1.3) and you get 286.
