Question

Q7 Solve the following problems. 1)4/5 + 6/5 2)4/5-7/15 3)3/5×2/5 4)3/5÷2/5​

Answer 1

Answer:

1)4/5 + 6/5 = (4+6)/5 = 10/5 = 2

2)4/5-7/15 = (12-7) /15 = 5/15 = 1/3

3)3/5×2/5 = 6/25

4)3/5÷2/5 = (3/5)(5/2) = 3/2

Answer 2

Answer:

$\frac{4}{5} + \frac{6}{5 } = \frac{10}{5} = 2$

$\frac{4}{5} + \frac{7}{15} = \frac{19}{15}$

$\frac{3}{5} \times \frac{2}{5} = \frac{6}{25}$

$\frac{3}{5} \div \frac{2 }{5} = \frac{3}{5} \times \frac{5}{2} = \frac{3}{2}$
