Answer:

2.5 x 13.7 = 34.25

4.9 + 1.6 = 6.5

Step-by-step 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
