0.75/x = 5/8 By cross multiplying, we get 5x = 0.75*8 Therefore, x= 6/5 = 1.2

0.75 : x :: 5:8 is a proportion. If two ratios are equal then it is called a proportion. The above proportion can now be represented as (0.75/x) = (5/8)on cross multiplication, we will get (0.75 * 8 ) = (5 *x) --> 6 = (5*x) --> x = 6/5 --> x = 1.2

If a:b::c:d then ad= bc. Therefore, 0.75:x::5:8 implies 5x=8*0.75 i.e., x=6/5=1.20.

0.75/x = 5/8 (0.75*8) = (5*x). x= (0.75*8)/5 x=0.15 *8 x= 1.2

Given can be written as (0.75/x)=(5/8) Cross-multiply both (0.75*8)=(5x) So, (6/5) = x X=1.2

0.75/x = 5/8. x=0.75 x 8 /5 which comes to be 6/5 = 1.2.
