Question

Which sum is equal to 3 1/4+1 2/5?

Answer 1

Answer:

$\huge\boxed{\bf\: \frac{93}{20}=4.65}$

Step-by-step explanation:

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

Now,

$3 \frac { 1 } { 4 } \\= \frac{4 * 3+1}{4}\\= \frac{13}{4}$

Then,

$1 \frac { 2 } { 5 }\\= \frac{1* 5+2}{5} \\= \frac{7}{5}$

So,

$3 \frac { 1 } { 4 } + 1 \frac { 2 } { 5 }\\= \frac{13}{4}+\frac{7}{5}\\ \\\mathrm{LCM = 20}\\\\= \frac{65}{20}+\frac{28}{20} \\=\boxed{\bf\: \frac{93}{20}=4.65}$
