Why do we do x x 5 and 0.75 x 8?
Why isn't it 0.75 x 5 and x x 8?

0.75 change new with no like after 0 two digit found we do like 75/100*8 = 6.

When we see :: in between,
a:b :: c:d.
Formula is a*d=b*c .so, by given values we can find x, here they gave a, c, d values
we need to find b, according to formula.
0.75*8=5*x.
x=6/5 which is 1.2.
@Janu hope you got it.

The answer is 1.20.
We have to do cross multiply here

The product of means equals to product of extremes,
5 * x = 0.75 * 8,
5x = 6,
x=6/5,
x=1.2.
5 * x = 0.75 * 8,
5x = 6,
x=6/5,
x=1.2.

0.75 : x :: 5 : 8.
0.75/x = 5/8.
5x = 0.75 * 8,
X = 0.75 * 8/5,
X = 1.20.
0.75/x = 5/8.
5x = 0.75 * 8,
X = 0.75 * 8/5,
X = 1.20.

a/b = c/d.
0.75/x = 5/8.
(0.75 * 8)/5 =x,
6/5= x.
1.2 =x.
0.75/x = 5/8.
(0.75 * 8)/5 =x,
6/5= x.
1.2 =x.

5x = 0.75*8,
5x = 6.00,
x = 6.00/5,
x = 1.2.
5x = 6.00,
x = 6.00/5,
x = 1.2.
