Page 19 Problem 10 Answer
We need to divide 5/6 and 1/2 and express it in a simpler form.
Dividing by a number is the same as multiplying by its reciprocal.
When dividing by a fraction, we must first rewrite it as multiplying by its reciprocal:
⇒ \(\frac{5}{6} \div \frac{1}{2}=\frac{5}{6} \cdot \frac{2}{1}\)
⇒ \(\frac{10}{6}\)
Reduce the fraction by dividing the numerator and denominator by their GCF of 2;
⇒ \(\frac{10 \div 2}{6 \div 2}=\frac{5}{3}\)
⇒ \(1 \frac{2}{3} .\)
The quotient of 5/6 and 1/2 equals 1×2/3.

Given: Mrs. Marks has 3/4 pound of cheese to make sandwiches. She needs1/32 pounds of cheese for each sandwich.
We need to find the number of sandwiches she can make.
We will use the division of fractions to solve this.
We need to divide the total amount of cheese by the amount of cheese on each sandwich
⇒ \(\frac{3}{4} \div \frac{1}{32}\)
when dividing by a fraction we must first rewrite it as multiplying by its reciprocal
⇒ \(\frac{3}{4} \div \frac{1}{32}=\frac{3}{4} \cdot 32\)
Multiplying then gives:
⇒ \(\frac{3}{4} \cdot 32=3 \cdot \frac{32}{4}\)
= 3 . 8
= 24 Sandwiches
Mrs. Marks can make a total of 24 sandwiches with the cheese she has.
