Identify Fractions: Identify the fractions to be added. $\newline$ Carly spent $\frac{3}{4}$ of her minutes talking to her mom and $\frac{1}{8}$ of her minutes talking to her best friend. We need to add these fractions to find the total fraction of minutes spent. $\newline$ Calculation: $\frac{3}{4} + \frac{1}{8}$
Find Common Denominator: Find a common denominator. $\newline$ The denominators are $4$ and $8$ . The least common denominator (LCD) is $8$ . $\newline$ Calculation: Convert $\frac{3}{4}$ to a fraction with denominator $8$ . $\newline$ $\frac{3}{4} = \frac{(3\times2)}{(4\times2)} = \frac{6}{8}$
Add Fractions: Add the fractions. $\newline$ Now, add $\frac{6}{8}$ (from Step $2$ ) and $\frac{1}{8}$ . $\newline$ Calculation: $\frac{6}{8} + \frac{1}{8} = \frac{7}{8}$
