Example Question #231 : Fractions

Solve the equation:

\(\displaystyle \frac{20}{80}+\frac{11}{80}=\)

Possible Answers:

\(\displaystyle \frac{7}{8}\)

\(\displaystyle \frac{11}{80}\)

\(\displaystyle 31\)

\(\displaystyle \frac{16}{80}\)

\(\displaystyle \frac{31}{80}\)

Correct answer:

\(\displaystyle \frac{31}{80}\)

Explanation:

When adding fractions that have the same denominator, only the numerators are added together. Add the numerators and keep the denominators:

\(\displaystyle \frac{20}{80}+\frac{11}{80}=\frac{31}{80}\)

Answer: \(\displaystyle \frac{31}{80}\)

Example Question #1361 : Isee Middle Level (Grades 7 8) Mathematics Achievement

Solve the equation:

\(\displaystyle \frac{3}{14}+\frac{6}{14}=\)

Possible Answers:

\(\displaystyle 9\)

\(\displaystyle \frac{9}{14}\)

\(\displaystyle \frac{9}{28}\)

\(\displaystyle \frac{3}{14}\)

\(\displaystyle 14\)

Correct answer:

\(\displaystyle \frac{9}{14}\)

Explanation:

When adding fractions that have the same denominator, add the numerators only. To solve add the numerators and keep the denominators the same:

\(\displaystyle \frac{3}{14} +\frac{6}{14}=\frac{9}{14}\)

Answer: \(\displaystyle \frac{9}{14}\)

Example Question #1363 : Isee Middle Level (Grades 7 8) Mathematics Achievement

Solve the equation:

\(\displaystyle \frac{3}{12}+\frac{8}{12}=\)

Possible Answers:

\(\displaystyle 12\)

\(\displaystyle \frac{11}{12}\)

\(\displaystyle \frac{3}{4}\)

\(\displaystyle 11\)

\(\displaystyle \frac{5}{12}\)

Correct answer:

\(\displaystyle \frac{11}{12}\)

Explanation:

When adding fractions that have the same denominator, only the top numbers are summed. Add the numerators and leave the denominators the same:

\(\displaystyle \frac{3}{12}+\frac{8}{12}=\frac{11}{12}\)

Answer: \(\displaystyle \frac{11}{12}\)

Example Question #711 : Numbers And Operations

Solve the equation:

\(\displaystyle \frac{17}{70}+\frac{10}{70}=\)

Possible Answers:

\(\displaystyle \frac{27}{70}\)

\(\displaystyle \frac{7}{70}\)

\(\displaystyle \frac{9}{10}\)

\(\displaystyle 27\)

\(\displaystyle 70\)

Correct answer:

\(\displaystyle \frac{27}{70}\)

Explanation:

When adding fractions that have the same denominator, only the top numbers are summed. Add the numerators and leave the denominators the same:

\(\displaystyle \frac{17}{70}+\frac{10}{70}=\frac{27}{70}\)

Answer: \(\displaystyle \frac{27}{70}\)

Example Question #712 : Numbers And Operations

Add: \(\displaystyle \frac{52}{90}+\frac{10}{90}=\)

Possible Answers:

\(\displaystyle \frac{42}{90}\)

\(\displaystyle \frac{31}{45}\)

\(\displaystyle 62\)

\(\displaystyle 42\)

\(\displaystyle \frac{62}{180}\)

Correct answer:

\(\displaystyle \frac{31}{45}\)

Explanation:

Add the numerators and keep the denominators the same:

\(\displaystyle \frac{52}{90}+\frac{10}{90}=\frac{62}{90}\)

Reduce the fraction: \(\displaystyle \frac{62\div 2}{90\div 2}=\frac{31}{45}\)
