Question

If 3 3/4 lb. of candy cost $20.25, how much would 1 lb. of candy cost.

Answer 1

20.25 divided by 3.75 = 5.40

Answer 2

3 3/4 lb of candy costs $ 20.25

we have been given a mixed fraction with both whole number and fraction

so lets convert it an improper fraction

3 3/4

3 wholes are equivalent to $3*\frac{4}{4} = \frac{12}{4}$

then 3 3/4 is - $\frac{12}{4} + \frac{3}{4} = \frac{15}{4}$

so 15/4 lbs -- $ 20.25

then 1 lb is -- $\frac{20.25}{15/4} = \frac{20.25*4}{15} = \frac{81}{15} = 5.4$

therefore 1 lb is equal to $ 5.40
