Question

9 what is the quotient of 11.25 divided by 2.5 ? a 0.405 b 0.450 c 4.050 d 4.500

Explanation:

Step1: Set up division

We need to calculate \( 11.25 \div 2.5 \). To make this easier, we can multiply both the numerator and the denominator by 10 to eliminate the decimal in the divisor. So we get \( \frac{11.25\times10}{2.5\times10}=\frac{112.5}{25} \).

Step2: Perform division

Now we divide 112.5 by 25. \( 25\times4 = 100 \), and \( 112.5 - 100 = 12.5 \). Then \( 12.5\div25 = 0.5 \). So adding the two parts together, \( 4 + 0.5 = 4.5 \).

Answer:

D. 4.500
