Answer:
16/35
Step-by-step explanation:
since the denominators are different for both fractions, change the denominator.
2/5= 14/35
3/7= 15/35
15/35+ 14/35= 19/35
35- 19= 16
bearing in mind that a whole is just 1 = 25/25 = same/same and so on.
well, let's see first off, how much of the house was painted in total, 2/5 + 3/7, and the remaining is just the whole minus that.
