Answer 1

`7* 1(3)/(4)=12.25`

or

`7* 1(3)/(4)=12(1)/(4)`

Explanation:

Given:

The given equation is
`7* 1(3)/(4)`

Rewrite the given equation as

`= 7* 1(3)/(4)`

We write the mixed number is an addition of its whole and fractional parts

`= 7* (1+(3)/(4))`

Now we Write 1 as a fraction with a common denominator.

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

Now we join the numerators over the common denominator.

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

`= 7* (7)/(4)`

`= (7* 7)/(4)`

`= (49)/(4)`

`= (49)/(4)`

`= 12.25`

or
`=12(1)/(4)`

Therefore the answer of the given equation is
`=12(1)/(4)` or
`= 12.25`.
