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 [tex]\frac{1}{2}[/tex] ⇒ [tex]\frac{23}{2}[/tex]
1 [tex]\frac{3}{4}[/tex] ⇒ [tex]\frac{7}{4}[/tex]
Next, we must divide these two fractions:
[tex]\frac{23}{2}[/tex] ÷ [tex]\frac{7}{4}[/tex]
We must flip the divisor into a reciprocal:
[tex]\frac{23}{2}[/tex] ÷ [tex]\frac{4}{7}[/tex]
Change the division sign to multiplication and multiply:
[tex]\frac{23}{2}[/tex] × [tex]\frac{4}{7}[/tex] = [tex]\frac{92}{14}[/tex]
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)
