Chapter 4.4, Problem 14E

To determine

To find LCD

Answer to Problem 14E

  $\frac{3}{4}$ is greater than $\frac{7}{10}$ .

Explanation of Solution

Given information: $\frac{3}{4},\frac{7}{10}$

Formula Used: Factorisation

Calculation:

Convert these fractions to equivalent fractions with common denominator in order to compare them more easily.

LCM of 4 and 10 is 20

So ,denominator of both fractions 20.

  $\frac{3\times 5}{4\times 5}=\frac{15}{20}$

  $\frac{7\times 2}{10\times 2}=\frac{14}{20}$

  $\frac{15}{20}>\frac{14}{20}$

So, $\frac{3}{4}$ is greater than $\frac{7}{10}$ .
