Question

What is 42% of 150?

Answer 1

63

Explanation:

We can rewrite this problem as an expression.

`x = 150 * 0.42`

Now just multiply to find x

`x = 63`

Answer 2

`63`

Explanation:

We can set up the following ratio:

`42/100=x/150`

Which compares the percent to the number we're trying to take the percent of. We can cross multiply and we get:

`x=(42*150)/100`

Dividing both top terms by `2` and dividing the bottom by `4` (because we divided by `2` twice on top)

`x=(color(blue)(21)cancel42*color(blue)(75)cancel150)/(color(blue)(25)cancel100)`

`x=63`

Therefore, `42%` of `150` is `63`

Hope this helps!
