Question

Find the sum or difference in simplest form 1 3/7 + 10 6/7

Answer 1

Answer:

$12\frac{2}{7}$

Step-by-step explanation:

we have

$1\frac{3}{7} +10\frac{6}{7}$

step 1

Convert mixed number to an improper fraction

$1\frac{3}{7}=\frac{1*7+3}{7}=\frac{10}{7}$  

$10\frac{6}{7}=\frac{10*7+6}{7}=\frac{76}{7}$

step 2

Substitute in the expression above and find the sum

$\frac{10}{7}+\frac{76}{7}=\frac{86}{7}$

Convert to mixed number

$\frac{86}{7}=\frac{84}{7}+\frac{2}{7}=12\frac{2}{7}$
