Question

Check for closure property
1. For addition a = 3/7 b = 5/6
2. For division a = 1/13 b = 13/15​

Answer 1

Answer:

1)

$a = \frac{3}{7} \\ b = \frac{5}{6} \\ a + b = \frac{18 + 35}{42} = \frac{53}{42}$

2)

$\frac{1}{13} \div \frac{13}{15} \\ \frac{1}{13} \times \frac{15}{13} = \frac{15}{169}$
