Make sure they have all common denominators
\(\frac{2}{4} + \frac{4}{5} - \frac{7}{10}\)
\(\frac{2}{4} * \frac{5}{5} = \frac{10}{20}\)
\(\frac{4}{5} * \frac{4}{4} = \frac{16}{20}\)
\(\frac{7}{10} * \frac{2}{2} = \frac{14}{20}\)
\(\frac{10}{20} + \frac{16}{20} - \frac{14}{20}\)
Add \(\frac{10}{20} + \frac{16}{20} = \frac{26}{20}\)
\(\frac{26}{20} - \frac{14}{20} = \frac{12}{20}\)
To simplify, you must find the largest common factor which 4
In \(\frac{12}{20}\)
12÷4=3 and 20÷4=5
The answer is \(\frac{3}{5}\)
