To write the ratio as a fraction in the simplest form, the first step is to write both decimal values as fractions:


4.5=(9)/(2)
2.7=(27)/(10)

Next, divide the first value of the ratio by the second value:


(9)/(2)/(27)/(10)

To divide two fractions, you have to multiply the first fraction (dividend) by the reciprocal of the second fraction (divisor)


(9)/(2)\cdot(10)/(27)=(9\cdot10)/(2\cdot27)=(90)/(54)

Now you can simplify the fraction, 90 and 54 are multiples of 18. To simplify the fraction you have to divide the numerator and denominator by 18:


(90/18)/(54/18)=(5)/(3)

The ratio expressed as a fraction in its simplest form is:


(5)/(3)
