Question

1 1/4 + 1 1/2= write as a fraction and as a decimal.

Answer 1

Given:

The expression is,

`1(1)/(4)+1(1)/(2)=`

The objective is to write the result as both fraction and a decimal.

Step-by-step explanation:

To find fraction:

The addition can be performed as,

`\begin{gathered} 1(1)/(4)+1(1)/(2)=(4+1)/(4)+(2+1)/(2) \\ =(5)/(4)+(3)/(2)((2)/(2)) \\ =(5)/(4)+(6)/(4) \\ =(11)/(4) \end{gathered}`

To find decimal:

The decimal value of the fraction will be,

`(11)/(4)=2.75`

Hence, the fraction is (11/4) and decimal value is 2.75.
