Question

3/4 of a numbe is equal to 1/2 of an another number. The sum of two numbers is 50.What are these number? With explain​

Answer 1

Answer:

the first number is 20

the other number is 30

Step-by-step explanation:

let the number be x

let the other number be y

∴  $\frac{3x}{4}$ = $\frac{y}{2}$

= $\frac{3x}{4}$- $\frac{y}{2}$ =0

$\frac{3x-2y}{4}$=0

3x-2y=0------→1

it eq 2,

x+y=50---------→2

from 1 and 2,

3x-2y=0

x+ y=50

-------------

3x-2y=0

2x+2y=100            (∵multipling by 2)

----------------

5x=100

-----------------

x=20

x+y=50

∴y=50-20=30

Hope it helps!
