Question

Rajiv eaten 3/8 portion of gauva he having. Sanjiv eaten 2/5 portion of gauva he having. What portion did both have eaten altogether ?​

Answer 1

L.C.M=40

3/8*5/5=15/40

2/5*8/8=16/40

15/40+16/40=31/40

they ate 31/40 part of gauva

hope it helps you

Answer 2

Answer:

$\bold{\frac{31}{40}}$

Step-by-step explanation:

$\orange{\dagger} \red{\underline{Question:-}}$

Rajiv eaten 3/8 portion of gauva he having. Sanjiv eaten 2/5 portion of gauva he having. What portion did both have eaten altogether?

$\orange{\dagger} \red{\underline{Solution:-}}$

$\bold{Rajiv \:eaten=\frac{3}{8}\:path \:of\:gauva}$

$\bold{Sanjiv \:eaten=\frac{2}{5}\:portion\: \:of\:gauva}$

Now,we should add the both the fractions because they ask altogether

$\Rightarrow \bold{\frac{3}{8} +\frac{2}{5} }$

Denominators are different then we should do LCM

LCM of 8 and 5 is

Multiples of 8 = $8,16,24,32,\red{40},48,5,.64,72,80$

Multiples of 5 = $5,10,15.20,25,30,35,\red{40},45,50$

$\bigstar$ Common factor is = 40

$\bold{LCM\:of\:8,5\:is\:40}$

$\Rightarrow \bold{\frac{5\times3\:+\:8\times2}{40}}$

$\Rightarrow \bold{\frac{15+16}{40}}$

$\Rightarrow \bold{\frac{31}{40}}$

$\pink{Therefore,they\:\:eaten\:\:altogether = \frac{31}{40}}$
