Question

3/5 + 2/7 solve this number ​

Answer 1

Answer:

= 3/5+2/7

The L.C.M of both 5 & 7 is 35.

So, = [(3×7)+(2×5)]/35

= (21+10)/35

= 31/35

Answer 2

Answer:

0.8857

Step-by-step explanation:

$\frac{3}{5} + \frac{2}{7} \\ so \: now \: we \: shud \: make \: both \: the \: denominators \: equal \\ so \: he \: lcm \: of \: 5 \: and \: 7 \: is \: 35 \\ \frac{3}{5} \times \frac{7}{7} = \frac{21}{35} \\ \frac{2}{7} \times \frac{5}{5} = \frac{10}{35} \\ so \: know \: both \: the \: denomnators \: are \: same \: and \: so \: we \: can \: add \: and \: simplify \: he \: solution \\ \frac{21}{35} + \frac{10}{35} = 31 \div 35 = 0.8857...$
