Question

150 percent of what number is 18

Answer 1

150% of 12 would be 18. because if you have 12 you are left with 6, this is 50%. now if you add the 12(100%) with the 6 (50%) you get 18(150%)

Answer 2

150%
percent measns parts out of 100
150%=150/100=1.5

'of' means multiply
150% of what is 18
1.5 times what=18
divide both sides by 1.5
what=12
the number is 12
