14 3/12 - 5

Answer 1

To perform the subtraction $14\frac{3}{12}-5$, start by converting the mixed number into an improper fraction.

1. Convert $14\frac{3}{12}$ to an improper fraction: $$14\frac{3}{12}=\frac{(14\times 12)+3}{12}=\frac{168+3}{12}=\frac{171}{12}$$

2. Convert $5$ to a fraction with a denominator of $12$: $$5=\frac{5\times 12}{12}=\frac{60}{12}$$

3. Now subtract the two fractions: $$\frac{171}{12}-\frac{60}{12}=\frac{171-60}{12}=\frac{111}{12}$$

4. Convert $\frac{111}{12}$ back to a mixed number: $$111÷12=9\text{(whole number part)},\text{remainder: }111-(9\times 12)=3$$ So, $$\frac{111}{12}=9\frac{3}{12}$$

5. Simplify $\frac{3}{12}$: $$\frac{3}{12}=\frac{1}{4}$$

Thus, the final answer is: $$9\frac{1}{4}$$

So, $14\frac{3}{12}-5=9\frac{1}{4}$.
