Example Question #1351 : Isee Middle Level (Grades 7 8) Mathematics Achievement

\(\displaystyle \frac{22}{29}+\frac{36}{29}=\)

Possible Answers:

\(\displaystyle 2\)

\(\displaystyle \frac{32}{29}\)

\(\displaystyle \frac{10}{29}\)

\(\displaystyle 1\)

Correct answer:

\(\displaystyle 2\)

Explanation:

Add the numerators and keep the denominator the same. Then, reduce:

\(\displaystyle \frac{22}{29}+\frac{36}{29}=\frac{58}{29}=2\)

Answer: \(\displaystyle 2\)

Example Question #1352 : Isee Middle Level (Grades 7 8) Mathematics Achievement

\(\displaystyle \frac{6}{13}+\frac{7}{13}=\)

Possible Answers:

\(\displaystyle 11\)

\(\displaystyle 1\)

\(\displaystyle \frac{1}{13}\)

\(\displaystyle 13\)

Correct answer:

\(\displaystyle 1\)

Explanation:

Add the numerators and keep the denominator; then, reduce:

\(\displaystyle \frac{6}{13}+\frac{7}{13}=\frac{13}{13}=1\)

Answer: \(\displaystyle 1\)

Example Question #1353 : Isee Middle Level (Grades 7 8) Mathematics Achievement

Solve:
\(\displaystyle \frac{1}{4}+\frac{3}{7}=\)

Possible Answers:

\(\displaystyle \frac{19}{28}\)

\(\displaystyle \frac{4}{11}\)

\(\displaystyle \frac{3}{28}\)

\(\displaystyle \frac{3}{19}\)

Correct answer:

\(\displaystyle \frac{19}{28}\)

Explanation:

The least common denominator of \(\displaystyle 7\) and \(\displaystyle 4\) is \(\displaystyle 28\).

\(\displaystyle \frac{1}{4}=\frac{7}{28}\)

\(\displaystyle \frac{3}{7}=\frac{12}{28}\)

\(\displaystyle \frac{7}{28}+\frac{12}{28}=\frac{19}{28}\)

Example Question #1353 : Isee Middle Level (Grades 7 8) Mathematics Achievement

\(\displaystyle \frac{30}{75}+\frac{11}{75}=\)

Possible Answers:

\(\displaystyle 41\)

\(\displaystyle \frac{19}{75}\)

\(\displaystyle 11\)

\(\displaystyle \frac{41}{75}\)

Correct answer:

\(\displaystyle \frac{41}{75}\)

Explanation:

Add the numerators and keep the denominator the same:

\(\displaystyle \frac{30}{75}+\frac{11}{75}=\frac{41}{75}\)

Answer: \(\displaystyle \frac{41}{75}\)

Example Question #1354 : Isee Middle Level (Grades 7 8) Mathematics Achievement

\(\displaystyle \frac{51}{80}+\frac{20}{80}=\)

Possible Answers:

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

\(\displaystyle \frac{71}{80}\)

\(\displaystyle \frac{51}{80}\)

\(\displaystyle \frac{20}{80}\)

Correct answer:

\(\displaystyle \frac{71}{80}\)

Explanation:

Add the numerators and keep the denominator the same:

\(\displaystyle \frac{51}{80}+\frac{20}{80}=\frac{71}{80}\)

Answer: \(\displaystyle \frac{71}{80}\)

Example Question #28 : How To Add Fractions

Add the fractions below.

 \(\displaystyle \frac{4}{5} + \frac{7}{10}\)

Possible Answers:

\(\displaystyle \frac{11}{15}\)

\(\displaystyle \frac{11}{10}\)

\(\displaystyle \frac{3}{2}\)

\(\displaystyle \frac{9}{5}\)

\(\displaystyle \frac{18}{5}\)

Correct answer:

\(\displaystyle \frac{3}{2}\)

Explanation:

First, we need to find a common denominator. In this case, we can convert both denominators to \(\displaystyle 10\).

\(\displaystyle \frac{4}{5} + \frac{7}{10} = (\frac{4 }{5 }*\frac{2}{2}) + \frac{7}{10} = \frac{8}{10} + \frac{7}{10}\)

Now we can add the numerators.

\(\displaystyle \frac{8}{10}+\frac{7}{10}=\frac{15}{10}\)

Both the numerator and denominator are divisible by \(\displaystyle 5\), so we can simplify.

\(\displaystyle \frac{15}{10}= \frac{15\div 5}{10\div 5}= \frac{3}{2}\)

Example Question #1355 : Isee Middle Level (Grades 7 8) Mathematics Achievement

Add: \(\displaystyle \frac{15}{24}+\frac{8}{24}=\)

Possible Answers:

\(\displaystyle \frac{7}{24}\)

\(\displaystyle 24\)

\(\displaystyle \frac{23}{24}\)

\(\displaystyle 1\)

\(\displaystyle 23\)

Correct answer:

\(\displaystyle \frac{23}{24}\)

Explanation:

To solve, add the numerators and leave the denominators the same:

\(\displaystyle \frac{15}{24}+\frac{8}{24}=\frac{23}{24}\)

Answer: \(\displaystyle \frac{23}{24}\)

Example Question #1356 : Isee Middle Level (Grades 7 8) Mathematics Achievement

Add: \(\displaystyle \frac{26}{78}+\frac{15}{78}=\)

Possible Answers:

\(\displaystyle \frac{41}{78}\)

\(\displaystyle 41\)

\(\displaystyle \frac{41}{156}\)

\(\displaystyle 78\)

\(\displaystyle \frac{11}{78}\)

Correct answer:

\(\displaystyle \frac{41}{78}\)

Explanation:

To solve, add the numerators and leave the denominators the same:

\(\displaystyle \frac{26}{78}+\frac{15}{78}=\frac{41}{78}\)

Answer: \(\displaystyle \frac{41}{78}\)
