Question

Ron used 1 3/4 cups of sugar in making a cake and 3/4 cup in making the icing. How much sugar did he use in all

Answer 1

The number of cups used in all is
`(5)/(2)`

Explanation:

Given : Ron used
`1(3)/(4)` cups of sugar in making a cake and
`1(3)/(4)` cup in making the icing.

To find : How much sugar did he use in all ?

Solution :

Number of cups used in making a cake is
`1(3)/(4)=(7)/(4)`

Number of cups used in making the icing is
`(3)/(4)`

Total number of cups used in all is

`T=(7)/(4)+(3)/(4)`

`T=(7+3)/(4)`

`T=(10)/(4)`

`T=(5)/(2)`

Therefore, The number of cups used in all is
`(5)/(2)`

Answer 2

Sugar used for making cake is 7/4

Sugar used for making icing is 3/4

Total sugar used = 7/4 + 3/4 = (7+3)/4

= 10/4 = 5/2
