Answer 2

Answer:

$8\frac{3}{4} +10\frac{2}{5}$ = $19\frac{3}{20}$

Step-by-step explanation:

Required to find the sum

$8\frac{3}{4} +10\frac{2}{5}$

Solution:

First convert the mixed fractions to normal fractions

$8\frac{3}{4}$ = $\frac{35}{4}$

$10\frac{2}{5} =\frac{52}{5}$

Then,

$8\frac{3}{4}$  + $10\frac{2}{5}$ = $\frac{35}{4} + \frac{52}{5}$

Taking LCM of the denominators, we get

LCM(4,5) = 4×5 = 20, since 4 and 5 are coprime

 $8\frac{3}{4}$  + $10\frac{2}{5}$   = $\frac{35X5+ 52X4}{20}$

= $\frac{175+208}{20}$

= $\frac{383}{20}$

= $19\frac{3}{20}$

∴ $8\frac{3}{4} +10\frac{2}{5}$ = $19\frac{3}{20}$
