\(1 \frac{3}{4} - \frac{7}{10}\)
We first have to change the mixed number into a fraction and we do this by multiplying the denominator to the whole number and adding the product to the numerator.
It looks something like this:
\(1 \frac{3}{4}\)
4×1=4 (Multiply the denominator and the whole number)
4+3=7 (Add the product and the numerator)
\(\frac{7}{4}\)
Keep the same denominator
Now that we have the improper fraction, we can subtract.
\(\frac{7}{4} - \frac{7}{10}\)
Now in order to subtract we have to have a common denominator, so lets make both of the denominators 20.
\(\frac{7}{4}\) × \(\frac{5}{5}\) = \(\frac{35}{20}\)
\(\frac{7}{10}\) × \(\frac{2}{2}\) = \(\frac{14}{20}\)
\(\frac{35}{20} - \frac{14}{20} = \frac{21}{20}\)
21÷20=1.05 or \(1 \frac{1}{20}\)
