Question

What is the sum of 1 7 10 and 3 3 5 ? Use the fraction strips to help.

Answer 1

Answer: $5\frac{3}{10}$

We first write them as improper fraction.

$1\frac{7}{10}=\frac{17}{10}$

$3\frac{3}{5}=\frac{18}{5}$

Then we find the LCM of the denominators. That is 10.

Using LCD we find the sum:

$1\frac{7}{10}+3\frac{3}{5}\\=\frac{17}{10}+\frac{18}{5}\\=\frac{17}{10}+\frac{36}{10}\\=\frac{53}{10}\\=5\frac{3}{10}$
