By adding fractions, we conclude that the correct option is the third one:
"one and two sevenths tubes"
How much red and blue paint does Mary have in total?
We know that:
- She has 5/7 of the red paint tube.
- She has 4/7 of the blue paint tube.
The total amount of paint will be given by the direct addition of these two fractions, notice that the denominator is the same in both cases, so we can just add the numerators.
5/7 + 4/7 = (5 + 4)/7 = 9/7
We can rewrite this as:
9/7 = 7/7 + 2/7 = 1 + 2/7
Thus, the correct option is the third one
"one and two sevenths tubes"
