The decimals 2.25 and 3.16 are respectively eequal to the fractions

We are given 2.25 and 3.16 and we have to convert them into fractions.

We can write them as
$$\begin{gathered} 2.25 = \frac{225}{100} \\ = \frac{5 \times 5 \times 3 \times 3}{2 \times 2 \times 5 \times 5 }, (5 \times 5 \mathrm{gets} \mathrm{cancelled} \mathrm{out} \mathrm{from} \mathrm{numerator} \mathrm{and} \mathrm{denominator}) \\ = \frac{3 \times 3}{2 \times 2 } = \frac{9}{4} \\ \mathrm{Now}, 3.16 = \frac{316}{100} \\ = \frac{2 \times 2 \times 79}{2 \times 2 \times 5 \times 5 }, (2 \times 2 \mathrm{gets} \mathrm{cancelled} \mathrm{out} \mathrm{from} \mathrm{numerator} \mathrm{and} \mathrm{denominator}) \\ = \frac{79}{25} \end{gathered}$$


Hence, the answer.
