Question

The zookeeper records how many scoops of peanuts she feeds the elephant for several days . Tuesday 21 Wednesday 19 5/8.

Answer 1

Step-by-step explanation:

We want to know the difference between the amount of scoops she fed the elephant on Wednesday and on Tuesday:

`21-19(5)/(8)`

We can write the second number as an improper fraction:

`21-(19\cdot(8)/(8)+(5)/(8))=21-((152)/(8)+(5)/(8))=21-(157)/(8)`

And now substract the two numbers:

`\begin{gathered} 21-(157)/(8)=(21\cdot8)/(8)-(157)/(8) \\ 21-(157)/(8)=(168)/(8)-(157)/(8) \\ 21-(157)/(8)=(168-157)/(8)=(11)/(8) \end{gathered}`

Answer:

She fed the elephant 11/8 scoops of peanuts more on Tuesday than on Wednesday
