Question

Write $3.5$ as fraction in its lowest terms.

Answer 1

Step 1. Write the decimal fraction with $1$ in the denominator

$3.5=\frac{3.5}{1}$

Step 2.Multiply by $10$ in both numerator and denominator or just add one zero in the denominator and remove decimal from the numerator.

$\frac{3.5x10}{1x10}=\frac{35}{10}$ or $\frac{35}{10}$

Step 3. To reduce the fraction divide the numerator and denominator by their HCF.

Therefore HCF of $35$ and $10=5$

So we have ,$\frac{35÷5}{10÷5}=\frac{7}{2}$

Hence $\frac{7}{2}$ is the fraction form of $3.5$ in its lowest term.
