Question

3 whole 1 by 5 + 2 whole 1 by 10 minus 1 whole 1 by 2 minus 1 by 4​

Answer 1

Solve

Step-by-step explanation:

$3\frac{1}{5} + 2 \frac{1}{10} - 1\frac{1}{2} -\frac{1}{4}$

Now, we will convert the mixed fraction into improper fraction

$\frac{16}{5} + \frac{21}{10} - \frac{3}{2} - \frac{1}{4}$

Now we will find the LCM of denominators.

LCM of 5, 10, 2 and 4 is 20.

Now,

= $\frac{64}{20} + \frac{42}{20} + \frac{30}{20} - \frac{5}{20}$

= $\frac{64+ 42 + 30 - 5 }{20}$

= $\frac{106 + 30 - 5 }{20}$

= $\frac{136 - 5 }{20}$

= $\frac{131 }{20}$

Now converting it into mixed form.

= $6\frac{11}{20}$

So, the answer is  $6\frac{11}{20}$.
