Question

A family drove 1/5 of the total distance to the coast on the first day. They drove 2/5 more of the distance to the coast on the second day. How much of the total distance had the family traveled on the two days? A. 2/25 B. 3/10 C. 3/5 D. 1/5

Answer 1

Your answer is c. 3/5. You just add 2/5 and 1/5 together (your denominator never changes when you are adding the same denominator). You would basically just do 2 + 1=3

Answer 2

travel distance on first day - 1/5 (0.2)
travel distance on second day - 2/5 (0.4)
total distance traveled on two days - 1/5+2/5 (or) 0.2+0.4

1/5+2/5 (or) 0.2+0.4
[as the two denominators are same we can just add the numerators]
3/5 (or) 0.6

Therefore, the family traveled 3/5 (0.6) on two days. So the answer is C. 3/5
