What is 9 divided by 1.25?

What is 9 divided by 1.25?

• A. 7.2
• B. 7.5
• C. 8
• D. 8.5

Answer: (A)

To find the solution to the problem, you start by understanding the division involved: dividing 9 by 1.25. First, it's helpful to convert the divisor (1.25) into a fraction for easier calculation. Since 1.25 can be expressed as 5/4, the problem then transforms into finding how many times 5/4 fits into 9. To solve this, you can multiply 9 by the reciprocal of 5/4, which is 4/5. This gives you: \[ 9 \times \frac{4}{5} = \frac{9 \times 4}{5} = \frac{36}{5} \] Now, performing the division: \[ \frac{36}{5} = 7.2 \] This indicates that when you divide 9 by 1.25, the quotient is indeed 7.2. Understanding this calculation method, you can confidently identify that this aligns with the provided choice of 7.2.
