Question

8 gallons equals how many pints?

Answer 1

Hint: For this type of word problem, we use the unitary method to solve it. Firstly, we start to solve the question by finding out the number of pints that are in 1 gallon. Then we need to perform cross-multiplication as used in the unitary method and then we simplify the expression to get the number of pints are in 8 gallons.

Complete step-by-step solution:
Gallon is used to measure the capacity of fluids or volume and is numerically equal to approximately 3.78541 litres.
Pints are used to measure for volume measurement of liquids. It is approximately equal to 0.473 litres.
In the Unitary method, we first find out the price of the single unit of commodity and then find the price for the successive units by simply multiplying against the price of a single unit.
We know that,
1 gallon = 8 pints
Here we are told to find out no of pints in 8 gallons which can be written in a unitary form as,
1 gallon -- 8 pints
8 gallons --? pints
Here we perform cross multiplication to find out the number of cups in 8 gallons.
On cross multiplying we get,
$\Rightarrow \dfrac{8\times 8}{1}$ pints
$\Rightarrow 64$ pints
Therefore, 64 pints are in 8 gallons.

Note: Here in our question, we have used the unitary method. While writing our values from the question in a unitary form, for simplification, always write the things to be calculated on the right-hand side and things known on the left-hand side. We can also use the ratio and proportion method to solve this question. Never forget to write the units of the quantity after the whole evaluation of the question. Units are what defines a quantity.
