Question

Three out of ten students in a band rent their instruments. If there are 350 band members, how many of the students rent their instrument? How do you solve it and get an answer?

Answer 1

Answer:

If there are 350 band members, 105 of the students rent their instrument.

Step-by-step explanation:

Given:

Three out of ten students in a band rent their instruments.

If there are 350 band members.

Now, to find the number of students rent their instrument.

As, given 3 out of 10 students in band rent their instruments.

So, the ratio is 3 : 10.

Now, if there are 350 band members.

Let the the number of students out of 350 rent their instrument be $x.$

If the ratio is 3 : 10.

So, 3 is equivalent to 10.

Thus, $x$ is equivalent to 350.

So, we set the proportion:

$3:10=x:350$

Now, to solve using cross multiplication method:

$\frac{3}{10} =\frac{x}{350}$

By cross multiplying we get:

$1050=10x$

Dividing by 10 on both sides we get:

$105=x$

$x=105.$

Therefore, if there are 350 band members 105 of the students rent their instrument.
