Question

when jeremiah looked at his cell phone bill for the month, he saw that he had spent 1/4 of his minutes talking to his mother and 1/8 of his minutes talking to his best friend. what fraction of the minutes did jeremiah spend talking to either his mom or his best friend? write your answer as a fraction or as a whole or mixed number.

Explanation:

Step1: Identify the fractions to add

We need to add the fraction of minutes talking to his mother ($\frac{1}{4}$) and the fraction talking to his best friend ($\frac{1}{8}$).

Step2: Find a common denominator

The least common denominator of 4 and 8 is 8. Convert $\frac{1}{4}$ to eighths: $\frac{1}{4}=\frac{1\times2}{4\times2}=\frac{2}{8}$.

Step3: Add the fractions

Now add $\frac{2}{8}$ and $\frac{1}{8}$: $\frac{2}{8}+\frac{1}{8}=\frac{2 + 1}{8}=\frac{3}{8}$.

Answer:

$\frac{3}{8}$
