To write and solve the proportion.

Answer to Problem 22CR

The proportion is written as: $\frac{2}{64}=\frac{x}{150}$

Number of buses required to carry 150 people is 5.

Explanation of Solution

Given information:

Number of buses required to carry 64 peoples is 2.

Calculation:

Let, $x$ be the number of buses required to carry 150 people.

Therefore,

The proportion is obtained as:

  $\frac{2}{64}=\frac{x}{150}$

Using cross product property,

  $\begin{array}{l}2\times 150=x\times 64\\ 300=64x\text{ [Multiply]}\end{array}$

Divide each side by 64,

  $\begin{array}{l}\frac{300}{64}=\frac{64x}{64}\\ x=4.6875\approx 5\text{ [Simplify]}\end{array}$
