Question

simplify 3 by 7 + 5/ 9 - (- 2/ 3)​

Answer 1

Answer:

32/9 is the correct answer

Answer 2

Solution :-

$\frac{3}{7} + \frac{5}{9} - ( - \frac{2}{3} )$

$\longrightarrow \frac{3}{7} + \frac{5}{9} + \frac{2}{3}$

$\longrightarrow \frac{9 \times 3 + 5 \times 7}{63} + \frac{2}{3}$

$\longrightarrow \frac{27 + 35}{63} + \frac{2}{3}$

$\longrightarrow \frac{62}{63} + \frac{2}{3}$

$\longrightarrow \frac{62 + 2 \times 21}{63}$

$\longrightarrow \frac{62 + 42}{63}$

$\longrightarrow \frac{104}{63}$

$\longrightarrow 1.65$
