Add. 9/10 + 1/5=_____

Identify Common Denominator: Identify a common denominator for 9/10 and 1/5. The denominators are 10 and 5. The least common denominator (LCD) for these two fractions is 10 because 10 is the smallest number that both 5 and 10 can divide into without leaving a remainder.Convert to Common Denominator: Convert 1/5 to a fraction with the common denominator of 10. To convert 1/5 to a fraction with a denominator of 10, multiply both the numerator and the denominator by 2. 1/5 * (2/2) = 2/10Add Fractions: Add the two fractions with the common denominator. Now that both fractions have the same denominator, you can add them together. 9/10 + 2/10 = (9+2)/10Perform Numerator Addition: Perform the addition of the numerators. Add the numerators together. 9 + 2 = 11 So, 9/10 + 2/10 = 11/10Simplify Fraction: Simplify the fraction if possible. The fraction 11/10 is already in its simplest form because the numerator and denominator have no common factors other than 1.

\frac{9}{10} + \frac{1}{5}=

_____

Identify Common Denominator: Identify a common denominator for $\frac{9}{10}$ and $\frac{1}{5}$ . The denominators are $10$ and $5$ . The least common denominator (LCD) for these two fractions is $10$ because $10$ is the smallest number that both $5$ and $10$ can divide into without leaving a remainder.
Convert to Common Denominator: Convert $\frac{1}{5}$ to a fraction with the common denominator of $10$ . To convert $\frac{1}{5}$ to a fraction with a denominator of $10$ , multiply both the numerator and the denominator by $2$ . $\frac{1}{5} \times \left(\frac{2}{2}\right) = \frac{2}{10}$
Add Fractions: Add the two fractions with the common denominator. $\newline$ Now that both fractions have the same denominator, you can add them together. $\newline$ $\frac{9}{10} + \frac{2}{10} = \frac{9+2}{10}$
Perform Numerator Addition: Perform the addition of the numerators. $\newline$ Add the numerators together. $\newline$ $9 + 2 = 11$ $\newline$ So, $\frac{9}{10} + \frac{2}{10} = \frac{11}{10}$
Simplify Fraction: Simplify the fraction if possible. $\newline$ The fraction $\frac{11}{10}$ is already in its simplest form because the numerator and denominator have no common factors other than $1$ .
