There's nothing to solve, it's simply an expression.
100*5/30 = 500/30 = 50/3 = 16.66... %
5x=30...then x=30/5. So X=6.
30% of 60 = 0.3 x 60 = 18

100*5/30 = 500/30 = 50/3 = 16.66... %
5x=30...then x=30/5. So X=6.
30% of 60 = 0.3 x 60 = 18
solve it
-35
solve? Use the rule IS / OF = % / 100 EX: What is 30% of 50? IS is the unknown = x, % = 30, OF = 50 x / 50 = 30/ 100 now solve the equation 100x = 1500 x = 15
We don't know what operation you want. 1 x 30 = 30 0 + 30 = 30 60 - 30 = 30 900/30 = 30
30% is the same as 0.3 so 0.3*40 = 12
