Question

To divide 14 2/3 ÷ 2 3/4, Erik multiplied 14 2/3 × 4/3 . Explain erik's error

Answer 1

Erik's error was that he forgot the 2 that was in the side of 3/4.

Answer 2

Erik did mistake in second term i.e.
`(4)/(3)`

Explanation:

Given expression,

`14(2)/(3)/ 2(3)/(4)`

`=(14(2)/(3))/(2(3)/(4))`

`=14(2)/(3)* (1)/(2(3)/(4))`

`=14(2)/(3)* (1)/((11)/(4))`

`=14(2)/(3)* (4)/(11)`

While,

Erick's result =
`14(2)/(3)* (4)/(3)`

Hence, he/she should write
`(4)/(11)` instead of
`(4)/(3)`
