Please note that in such questions, the ":" stands for ratio which in turn stands for divide. Thus, the given expression which is:
will become:
.....(Equation 1)
Now, we know that 3.8 can be rewritten as . Also, we know that the mixed fraction
can be re-written as:
Using the above two expressions in (Equation 1) we get:
Cross-multiplication gives:
Or c=0.25
Thus, we may write the value of c as either the decimal 0.25 or the fraction .
