0.72 / 9 show your work

1 answer

To divide \(0.72\) by \(9\), you can follow these steps:

  1. Set up the division: You want to find out how many times \(9\) fits into \(0.72\).

  2. Convert the division into a more manageable form: Since \(9\) is a whole number, you can rewrite the division as:

    \[ \frac{0.72}{9} \]

  3. Perform the division: You can express \(0.72\) as a fraction:

    \[ 0.72 = \frac{72}{100} \]

    So,

    \[ \frac{0.72}{9} = \frac{72/100}{9} = \frac{72}{100 \times 9} = \frac{72}{900} \]

  4. Simplify the fraction: Now, we simplify \(\frac{72}{900}\).

    • Find the greatest common divisor (GCD) of \(72\) and \(900\). The GCD is \(36\).

    • Divide both the numerator and the denominator by \(36\):

    \[ \frac{72 \div 36}{900 \div 36} = \frac{2}{25} \]

  5. Convert back to decimal, if needed: If you'd like the decimal form of this result, divide \(2\) by \(25\):

    \[ 2 \div 25 = 0.08 \]

Thus, the result of \(0.72\) divided by \(9\) is:

\[ \frac{0.72}{9} = 0.08 \]
