Question

In a survey of 2000 people, 1320 said they had a microwave. What percent of the people surveyed have a microwave?

Answer 1

= 1320/2000 x 100%
= 0.66 x 100%
= 66%

Answer 2

Lets first set up a proportion:

$\frac{1320}{2000} = \frac{p}{100}$

We could simplify the proportion to make the process easier:

$\frac{33}{50} = \frac{p}{100}$

Now we must multiply, 33×100 and 50×p:

$50p = 330$

Divide both sides by 50:

$p = 6.6$

Times it by 100

about 66% of the people own microwaves
