Answer:
[tex]7\times 1\frac{3}{4}=12.25[/tex]
or
[tex]7\times 1\frac{3}{4}=12\frac{1}{4}[/tex]
Step-by-step explanation:
Given:
The given equation is [tex]7\times 1\frac{3}{4}[/tex]
Rewrite the given equation as
[tex]= 7\times 1\frac{3}{4}[/tex]
We write the mixed number is an addition of its whole and fractional parts
[tex]= 7\times (1+\frac{3}{4})[/tex]
Now we Write 1 as a fraction with a common denominator.
[tex]= 7\times (\frac{4}{4}+\frac{3}{4})[/tex]
Now we join the numerators over the common denominator.
[tex]= 7\times \frac{4+3}{4}[/tex]
[tex]= 7\times \frac{7}{4}[/tex]
[tex]= \frac{7\times 7}{4}[/tex]
[tex]= \frac{49}{4}[/tex]
[tex]= \frac{49}{4}[/tex]
[tex]= 12.25[/tex]
or [tex]=12\frac{1}{4}[/tex]
Therefore the answer of the given equation is [tex]=12\frac{1}{4}[/tex] or [tex]= 12.25[/tex].
