An Italian sausage is 8 inches long. How many pieces of sausage can be cut from the 8-inch piece of sausage if each piece is to be two-thirds of an inch ?
Solution
Since you are trying to find out how many two-thirds there are in 8, it is a division of fractions problem.
So, divide 8 by 2/3
8 ÷ 2/3 = 8/1 ÷ 2/3 = 8/1 × 3/2 = 24/2 = 12
Therefore, you can make 12 pieces having a length of 2/3 inches
Example #2
How many halves are there in six-fourth?
Again, since you are trying to find out how many halves there are in six-fourth, it is a division of fractions problem.
So, divide 6/4 by 1/2
6/4 ÷ 1/2 = 6/4 × 2/1 = 12/4 = 3
Therefore, there are 3 halves in six-fourth
Example #3:
An airplane covers 50 miles in 1/5 hours. How many miles can the airplane cover in 5 hours?
This problem is a combination of division and multiplication of fractions
First, find out how many fifths (1/5) are there in 5. This is a division of fractions problem
So, divide 5 by 1/5
5 ÷ 1/5 = 5/1 ÷ 1/5 = 5/1 × 5/1 = 25/1 = 25
Then, multiply 50 by 25 to get 1250
In 5 hours, the airplane will cover 1250 miles
