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
[tex]25 * 10^{-1} * 137 * 10^{-1}[/tex]
= [tex]25*137*10^{-2}[/tex]
= [tex]3425 *10^{-2}[/tex]
= 34.25
Here we are just performing simple addition
4.9 + 1.6
= [tex]49 *10^{-1} +16*10^{-1}[/tex]
= [tex](49+16)*10^{-1}[/tex]
=[tex]65 * 10^{-1}[/tex]
= 6.5
