Chapter 7, Problem 1R

Write each ratio in lowest terms:

7 to 28

To determine

To calculate: The ratio $7\text{ to 28}$ in its lowest form.

Answer to Problem 1R

Solution:

The lowest form of ratio $7\text{ to 28}$ is $\frac{1}{4}$.

Explanation of Solution

Given Information:

The ratio is $7\text{ to 28}$.

Formula used:

The ratio of two number $a\text{ and b}$ can be written in several form such as $a\text{ to b}$, $\frac{a}{b}$, $a:b$ or $a÷\text{b}$.

Calculation:

The ratio $7\text{ to 28}$ can be written as,

$\begin{array}{c}7\text{ to 28}=\frac{7}{\text{28}}\\ =\frac{\cancel{7}\times 1}{\cancel{7}\times 4}\\ =\frac{1}{4}\end{array}$

Thus, the lowest form of ratio $7\text{ to 28}$ is $\frac{1}{4}$.
