Answer:

A

Step-by-step explanation:

28/100, because you make 3/10 into 30/100, then you add 45 and 30, then you subtract from 100, to get 28. Hope this helps!

Answer:

See below.

Step-by-step explanation:

3/10 converted to a fraction with a denominator of 100 would be 30/100.

30/100+42/100=72/100

100/100-72/100=28/100

The answer is A.
