Plz solve it CORRECTLY step by step​

Answer 1

`(6)/(10)ab`

Explanation:

Given that,

The first number is
`(-3a)/(7)`

The second number is
`(-21b)/(15)`

We need to find the product of the first number and second number. Product means we need to multiply i.e.

`(-3a)/(7)* (-21b)/(15)=0.6ab\\\\=(6)/(10)ab`

Hence, the product of the given numbers is equal to
`(6)/(10)ab`.
