$\frac{ \frac{8}{5} + ( - \frac{5}{6}) }{ \frac{1}{6} } \\ = \frac{ \frac{8}{5} - \frac{5}{6} }{ \frac{1}{6} } \\ = \frac{ \frac{48- 25}{30} }{ \frac{1}{6} } \\ = \frac{ \frac{23}{30} }{ \frac{1}{6} } \\ = \frac{23}{30} \times 6 \\ = \frac{23}{5}$

A gardener uses 1/3 of a liter of water to water 2/7 of a garden.

Serjik [45]

the gardener would need (1 + 1/6) liters of water to water the whole garden.

<h3>How much water would the gardener need to water the whole garden?</h3>

Here we know that the gardener needs 1/3 of a liter of water to water 2/7 of a garden.

Then we have the relation:

1/3 L = 2/7 of a garden.

Now, we want to get a "1 garden" in the right side of the equation, then we can multiply both sides by (7/2), so we get:

(7/2)*(1/3) L = (7/2)*(2/7) of a garden

(7/6)L = 1 garden.

(1 + 1/6) L = 1 garden

This means that the gardener would need (1 + 1/6) liters of water to water the whole garden.
