Question

What is 30 percent of 60

Answer 1

Answer: 18

Step-by-step explanation: Well percent means over 100 so we can set up an equation for this problem by reading it from left to right.

What means x, is means equals, 30% is 30/100, of means times 250.

Simplifying on the right side of the equation,

notice that 30/100 reduces to 3/10.

So we have x = 3/10 · 60. Think of the 60 as 60/1 so we can cross-cancel the 60 and 10 to 6 and 1 and we have x = $\frac{(3)(6)}{(1)(1)}$ or x = 18.

Now let's check our answer back in the original problem to see if it makes sense. We have 18 is 30% of 60.

Well we know that 100% of 60 would be 60 so 30% of 60 should be alot less than 60 so 18 seems to make sense as a pretty good answer.
