Answer 1

Answer:

$7\times 1\frac{3}{4}=12.25$

or

$7\times 1\frac{3}{4}=12\frac{1}{4}$

Step-by-step explanation:

Given:

The given equation is $7\times 1\frac{3}{4}$

Rewrite the given equation as

$= 7\times 1\frac{3}{4}$

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

$= 7\times (1+\frac{3}{4})$

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

$= 7\times (\frac{4}{4}+\frac{3}{4})$

Now we join the numerators over the common denominator.

$= 7\times \frac{4+3}{4}$

$= 7\times \frac{7}{4}$

$= \frac{7\times 7}{4}$

$= \frac{49}{4}$

$= \frac{49}{4}$

$= 12.25$

or $=12\frac{1}{4}$

Therefore the answer of the given equation is $=12\frac{1}{4}$ or $= 12.25$.
