Answer 2

Answer:

To Find :-

Difference between 4.5 and 2.75 in fraction form.

Solution :-

As we need difference in fraction form we need to conver two terms into fraction form.

4.5 =

As in decimal part there is one digit so,

multiplying 4.5 with 10 and dividing by 10.

$\sf\implies$ 4.5 × $\sf\frac{10}{10}$

$\sf\frac{45}{10}$

2.75 =

As in decimal part there are two digits so,

multiplying 2.75 with 100 and dividing by 100.

$\sf\implies$ 2.75 × $\sf\frac{100}{100}$

$\sf\frac{275}{100}$

Now difference,

$\frac{45}{10} - \frac{275}{100}$

Taking L.C.M,

L.C.M of 10,100 is 100.

so, again multiplying and dividing $\sf\frac{45}{10}$ with 10.

$\frac{45}{10} \times \frac{10}{10}$

$= \frac{450}{100}$

Difference,

$\frac{450}{100} - \frac{275}{100}$

$\frac{450 - 275}{100}$

$\frac{175}{100}$

$\sf\frac{\cancel{175}}{\cancel{100}}$

$\sf\frac{35}{20}$

$\frac{7}{4}$

Converting into Mixed Fraction,

We get , 1 $\sf\frac{3}{4}$

Hence,

Option '3'.
