Question

Aratati ca:
$(\frac{1}{3} + \frac{1}{5} ) \times \frac{3}{4} + \frac{3}{5} = 1$
​

Answer 1

$( \frac{1}{3} + \frac{1}{5} ) \times \frac{3}{4} + \frac{3}{5} = 1 \\ \frac{1}{3 } \times \frac{3}{4} + \frac{1}{5} \times \frac{3}{4} + \frac{3}{5} = 1 \\ \frac{1}{4 } + \frac{3}{20} + \frac{3}{5} = 1 \\ \frac{5 + 3 + 12}{20} = 1 \\ \frac{20}{20} = 1 = > 1 = 1$

Answer 2

(1/3+1/5)×3/4+3/5=1

8/15×3/4+3/5=1

2/15×3+3/5=1

2/5+3/5=1

(2+3)/5=1

5/5=1

1=1
