Answer

$\frac{9}{7}$

Work Step by Step

4.50 to 3.50 $\frac{4.50}{3.50}$ Now as decimals are in hundreds so multiply by 100 to get whole number. Then divide both numerator and denominator by 50. (4.50 × 100)/(3.50 ×100)= 450/350= (450 ÷ 50)/(350 ÷ 50)=$\frac{9}{7}$ It can be written as a fraction in the lowest term as $\frac{9}{7}$.
