Answer:
Mrs. Lopez made 50 quarts of sweet tea
Step-by-step explanation:
A gallon and a quart are two of the five US standard volumes of measurement. In relation to litres, a quart is 946.352946 millilitres while a gallon is 3.7854118 litres.
The relationship between The gallon and The quarts is given as 4:1
This means that for every 4 quarts, there is 1 gallon.
Now, let us find the number of quarts in 12¹/₂ gallons as follows:
1 gallon = 4 quarts
∴ 12¹/₂ gallons = 12¹/₂ × 4 quarts
converting the mixed fraction to improper fraction and multiplying:
= ²⁵/₂ × ⁴/₁
[tex]= \frac{25 \times 4 }{2 \times 1} = \frac{100}{2} \\\\= 50\ quarts[/tex]
