Solve 81/30

$$\frac { 81 } { 30 }$$

Evaluate

$$\frac{27}{10}=2.7$$

Steps For Long Division Method

Use the 1^{st} digit 8 from dividend 81

$$\begin{array}{l}\phantom{30)}\phantom{1}\\30\overline{)81}\\\end{array}$$

Since 8 is less than 30, use the next digit 1 from dividend 81 and add 0 to the quotient

$$\begin{array}{l}\phantom{30)}0\phantom{2}\\30\overline{)81}\\\end{array}$$

Use the 2^{nd} digit 1 from dividend 81

$$\begin{array}{l}\phantom{30)}0\phantom{3}\\30\overline{)81}\\\end{array}$$

Find closest multiple of 30 to 81. We see that 2 \times 30 = 60 is the nearest. Now subtract 60 from 81 to get reminder 21. Add 2 to quotient.

$$\begin{array}{l}\phantom{30)}02\phantom{4}\\30\overline{)81}\\\phantom{30)}\underline{\phantom{}60\phantom{}}\\\phantom{30)}21\\\end{array}$$

Since 21 is less than 30, stop the division. The reminder is 21. The topmost line 02 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 2.

$$\text{Quotient: }2 \text{Reminder: }21$$

Factor

$$\frac{3 ^ {3}}{2 \cdot 5} = 2\frac{7}{10} = 2.7$$
