Question

How much does 4 7/5 kg of candy cost if 5/6 kg costs 7.50

Answer 1

`\texttt{Cost for }4(7)/(5)kg=48.6`

Explanation:

Given that 5/6 kg candy costs 7.50.

That is

`\texttt{Cost for }(5)/(6)kg=7.5\\\\\texttt{Cost for 1 kg}=7.5* (6)/(5)=9`

Now we need to find cost for 4 7/5 kg of candy.

`\texttt{Cost for }4(7)/(5)kg=4(7)/(5)* 9\\\\\texttt{Cost for }4(7)/(5)kg=(4* 5+7)/(5)* 9=(27)/(5)* 9=48.6\\\\\texttt{Cost for }4(7)/(5)kg=48.6`

Answer 2

$48.60

4 7/5 is a funny way to express a fraction... but anway..... if this is correct, then the answer is as follows:

5/6 kg ------> cost $7.50

1 kg ----> costs $7.50 ÷ 5/6 kg = $9

4 7/5 kg ------> costs $9 x (4 7/5) = $9 x (27/5) = $48.60
