A piece of coaxial cable 23 m long is to be cut into 5 piece

A piece of coaxial cable 2/3 m long is to be cut into 5 pieces of the same length. What is the length of each piece? A recipe for muffins calls for 1/4 qt (quart) of buttermilk, 1/3 qt milk, and 1/16 qt of skin oil. How many quarts of liquid ingredients does the recipe call for?

Solution

2/5 m long
5 pieces of same length

So, each piece would be :
2/5 divided by 5

This is an example of dividingfractions......
We have to change divide to multiply and invert the second fraction

2/5 * 1/5

2/25 mtr is the length of each piece

---------------------------------------------------------------------

We gotta add them all

1/4 + 1/3 + 1/16

We have to add using LCD....
The LCD of 4 , 3 and 16 is 48

So, 1/4 is written as 12/48
1/3 as 16/48
1/16 as 3/48

Adding them :
(12 + 16 + 3)/48
31/48 quarts ----> ANSWER
