Question

Write the following comparison as a ratio reduced to lowest terms. 42 nickels to 36 dimes

Answer 1

We have the following:

We must convert the dimes into nickels, like this

$36\text{ dimes }\cdot\frac{2\text{ nickels}}{1\text{ dime}}=72\text{ nickels}$

Therefore, the ratio is:

$\frac{42}{72}=\frac{6\cdot7}{6\cdot12}=\frac{7}{12}$

The answer is 7/12
