Answer 1

Make equation to solve

Answer 2

Hi Bro....

Given :-
It is given that a number is 3/4 of second number.    .......(1)
Also, the sum of the two numbers is 70.                    .......(2)


First Step :-
Let the number be z.   (or any variable x, y, a, b or ......)

Second Step :-
Look at ....(1). The second number = 3/4 of first number.

Third Step :-
So, the second number will be $\frac{3}{4} X x$ = $\frac{3}{4} x$

Result (1) :-
Now, the two numbers are x and 3x/4.

Fourth Step :-
Now look at .....(2).  The sum of two numbers is 70.


Fifth Step :-
From Result (1) and Fourth Step, we formulate the below equation....

$x + \frac{3}{4} x = 70 \\ -\ \textgreater \ x + \frac{3x}{4} = 70$

Sixth Step :-
Taking LCM.
$-\ \textgreater \ \frac{4x}{4} + \frac{3x}{4}$
$-\ \textgreater \ \frac{7x}{4} = 70 \\ x = \frac{70 X 4}{7} \\ x = 40$

Result (2) :-
Hence, the number is 40.

Hope it helps.....
