Answer 1

Answer:

17.2

Answer 2

$\dfrac{2}{5} +\dfrac{3}{5} +\dfrac{11}{20}$ = $\dfrac{31}{20}$ or, 1.55

Step-by-step explanation:

We have,

$\dfrac{2}{5} +\dfrac{3}{5} +\dfrac{11}{20}$

To find, the value of $\dfrac{2}{5} +\dfrac{3}{5} +\dfrac{11}{20}$ = ?

∴ $\dfrac{2}{5} +\dfrac{3}{5} +\dfrac{11}{20}$

To take LCM of 5, 5 and 20

5 = 1 × 5 and

20 = 2 × 2 × 5 × 1

The  LCM of 5, 5 and 20 = 2 × 2 × 5 × 1 = 20

= $\dfrac{4\times 2+4\times 3+1\times 11}{20}$

= $\dfrac{8+12+11}{20}$

= $\dfrac{31}{20}$

= 1.55

∴ $\dfrac{2}{5} +\dfrac{3}{5} +\dfrac{11}{20}$ = $\dfrac{31}{20}$ or, 1.55
