Answer:

`\boxed{ \bf Sheila~will~need~about~7~containers.}`

Step-by-step explanation:

First, we will need to convert the mixed fractions to improper fractions.

Numerators: (2 · 11) + 1 = 23

(4 · 1) + 3 = 7

Denominators: stay the same.

11
`(1)/(2)` ⇒
`(23)/(2)`

1
`(3)/(4)` ⇒
`(7)/(4)`

Next, we must divide these two fractions:

`(23)/(2)` ÷
`(7)/(4)`

We must flip the divisor into a reciprocal:

`(23)/(2)` ÷
`(4)/(7)`

Change the division sign to multiplication and multiply:

`(23)/(2)` ×
`(4)/(7)` =
`(92)/(14)`

To find out how many containers will be needed, simply convert this fraction to a decimal by dividing the numerator by the denominator.

92 ÷ 14 = 7 (Rounded)
