Answer 1

2.5 x 13.7 = 34.25

4.9 + 1.6 = 6.5

Explanation:

Here we are multiplying 2 decimals we can just write it as

`25 * 10^(-1) * 137 * 10^(-1)`

=
`25*137*10^(-2)`

=
`3425 *10^(-2)`

= 34.25

Here we are just performing simple addition

4.9 + 1.6

=
`49 *10^(-1) +16*10^(-1)`

=
`(49+16)*10^(-1)`

=
`65 * 10^(-1)`

= 6.5
