Add. 4/12 + 5/12 = _____

Identify common denominators: Step 1: Identify common denominators. Both fractions have the same denominator, 12, so we can directly add the numerators. 4/12 + 5/12 = (4 + 5)/12Add numerators: Step 2: Add the numerators. 4 + 5 = 9 So, 4/12 + 5/12 = 9/12Simplify the fraction: Step 3: Simplify the fraction. 9/12 can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 3. 9 ÷ 3 = 3 and 12 ÷ 3 = 4 So, 9/12 simplifies to 3/4

Identify common denominators: Step $1$ : Identify common denominators. $\newline$ Both fractions have the same denominator, $12$ , so we can directly add the numerators. $\newline$ $\frac{4}{12} + \frac{5}{12} = \frac{(4 + 5)}{12}$
Add numerators: Step $2$ : Add the numerators. $\newline$ $4 + 5 = 9$ $\newline$ So, $\frac{4}{12} + \frac{5}{12} = \frac{9}{12}$
Simplify the fraction: Step $3$ : Simplify the fraction. $\newline$ $\frac{9}{12}$ can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is $3$ . $\newline$ $9 \div 3 = 3$ and $12 \div 3 = 4$ $\newline$ So, $\frac{9}{12}$ simplifies to $\frac{3}{4}$
