Question

Add.1)2upon5+1upon3 =
2) 2upon7 +1upon2​

Answer 1

Answer:

• 2/5 + 1/3 = 11/15
• 2/7 + 1/2 = 11/14

Step-by-step explanation:

If the base of the fraction is different in adding the fraction. Then find LCM and make denominator same and then add.

1) 2/5 + 1/3

LCM of 3 and 5 is 15.

$\frac{2}{5} = \frac{2 \times 3}{5\times 3} = \frac{6}{15} \\and \frac{1}{3} = \frac{1 \times 5}{3\times 5} = \frac{5}{15}\\\frac{2}{5} + \frac{1}{3} = \frac{6}{15} + \frac{5}{15}\\= \frac{6+ 5}{15}\\= \frac{11}{15}$

2) 2/7 + 1/2

LCM of 7 and 2 is 14.

$\frac{2}{7} = \frac{2 \times 2}{7\times 2} = \frac{4}{14} \\and \frac{1}{2} = \frac{1 \times 7}{2\times 7} = \frac{7}{14}\\\frac{2}{7} + \frac{1}{2} = \frac{4}{14} + \frac{7}{14}\\= \frac{4+ 7}{14}\\= \frac{11}{14}$
