Question

Estimate using compatible numbers.
seventy-eight percent of one hundred ninety-six

Answer 1

It is about 160.

You see, you can use the method: \[\frac{ is }{ of } = \frac{ percent }{ 100 }\]

The of is 196 since it is next to the word 'of'.

And the percent is 78%.

Now plug it in.\[\frac{ is }{ 196 } = \frac{ 78 }{ 100 }\]

You can solve for is by cross multiply.

So 196 x 78 is equal to 15288.

Divide it by 100 to get 152.88, which is close to about 160.
