lets find $\frac{3}{4}+\frac{1}{10}$. first write the addition with a common denominator. then add. $\frac{3}{4}+\frac{1}{10}=\frac{square}{square}+\frac{square}{square}=\frac{square}{square}$
Answer
Explanation:
Step1: Find the common denominator
The least - common multiple of 4 and 10 is 20.
Step2: Rewrite the fractions with the common denominator
$\frac{3}{4}=\frac{3\times5}{4\times5}=\frac{15}{20}$; $\frac{1}{10}=\frac{1\times2}{10\times2}=\frac{2}{20}$ So $\frac{3}{4}+\frac{1}{10}=\frac{15}{20}+\frac{2}{20}$
Step3: Add the fractions
$\frac{15}{20}+\frac{2}{20}=\frac{15 + 2}{20}=\frac{17}{20}$
Answer:
$\frac{15}{20}+\frac{2}{20}=\frac{17}{20}$
