Solve 80:72

$$80 : 72$$

Evaluate

$$\frac{10}{9}\approx 1.111111111$$

Steps For Long Division Method

Use the 1^{st} digit 8 from dividend 80

$$\begin{array}{l}\phantom{72)}\phantom{1}\\72\overline{)80}\\\end{array}$$

Since 8 is less than 72, use the next digit 0 from dividend 80 and add 0 to the quotient

$$\begin{array}{l}\phantom{72)}0\phantom{2}\\72\overline{)80}\\\end{array}$$

Use the 2^{nd} digit 0 from dividend 80

$$\begin{array}{l}\phantom{72)}0\phantom{3}\\72\overline{)80}\\\end{array}$$

Find closest multiple of 72 to 80. We see that 1 \times 72 = 72 is the nearest. Now subtract 72 from 80 to get reminder 8. Add 1 to quotient.

$$\begin{array}{l}\phantom{72)}01\phantom{4}\\72\overline{)80}\\\phantom{72)}\underline{\phantom{}72\phantom{}}\\\phantom{72)9}8\\\end{array}$$

Since 8 is less than 72, stop the division. The reminder is 8. The topmost line 01 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 1.

$$\text{Quotient: }1 \text{Reminder: }8$$

Factor

$$\frac{2 \cdot 5}{3 ^ {2}} = 1\frac{1}{9} = 1.1111111111111112$$
