A school will have a fall festival if at least 40% of the 500 students plan to attend. How many students must agree to attend in
artcher [175]

Answer:

200 students must agree to attend in order for the school to have the festival.

Step-by-step explanation:

200 is 40% of 500. We can also use fractions to figure this out.

\frac{40}{100} =\frac{x}{500}

For 100 to become 500 it must be multiplied by 5. And whatever we do to the denominator we have to do to the numerator. So we multiply 40 × 5 = <em>x</em>

<em>x</em> = 200

\frac{40*5}{100*5} = \frac{x}{500}      

\frac{40}{100} =\frac{200}{500}
