Solve 150:12=

$$150 : 12 =$$

Evaluate

$$\frac{25}{2}=12.5$$

Steps For Long Division Method

Use the 1^{st} digit 1 from dividend 150

$$\begin{array}{l}\phantom{12)}\phantom{1}\\12\overline{)150}\\\end{array}$$

Since 1 is less than 12, use the next digit 5 from dividend 150 and add 0 to the quotient

$$\begin{array}{l}\phantom{12)}0\phantom{2}\\12\overline{)150}\\\end{array}$$

Use the 2^{nd} digit 5 from dividend 150

$$\begin{array}{l}\phantom{12)}0\phantom{3}\\12\overline{)150}\\\end{array}$$

Find closest multiple of 12 to 15. We see that 1 \times 12 = 12 is the nearest. Now subtract 12 from 15 to get reminder 3. Add 1 to quotient.

$$\begin{array}{l}\phantom{12)}01\phantom{4}\\12\overline{)150}\\\phantom{12)}\underline{\phantom{}12\phantom{9}}\\\phantom{12)9}3\\\end{array}$$

Use the 3^{rd} digit 0 from dividend 150

$$\begin{array}{l}\phantom{12)}01\phantom{5}\\12\overline{)150}\\\phantom{12)}\underline{\phantom{}12\phantom{9}}\\\phantom{12)9}30\\\end{array}$$

Find closest multiple of 12 to 30. We see that 2 \times 12 = 24 is the nearest. Now subtract 24 from 30 to get reminder 6. Add 2 to quotient.

$$\begin{array}{l}\phantom{12)}012\phantom{6}\\12\overline{)150}\\\phantom{12)}\underline{\phantom{}12\phantom{9}}\\\phantom{12)9}30\\\phantom{12)}\underline{\phantom{9}24\phantom{}}\\\phantom{12)99}6\\\end{array}$$

Since 6 is less than 12, stop the division. The reminder is 6. The topmost line 012 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 12.

$$\text{Quotient: }12 \text{Reminder: }6$$

Factor

$$\frac{5 ^ {2}}{2} = 12\frac{1}{2} = 12.5$$
