[tex]1 \frac{3}{4} - \frac{7}{10} [/tex]
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:
[tex]1 \frac{3}{4} [/tex]
4×1=4 (Multiply the denominator and the whole number)
4+3=7 (Add the product and the numerator)
[tex] \frac{7}{4} [/tex]
Keep the same denominator
Now that we have the improper fraction, we can subtract.
[tex] \frac{7}{4} - \frac{7}{10} [/tex]
Now in order to subtract we have to have a common denominator, so lets make both of the denominators 20.
[tex] \frac{7}{4} [/tex] × [tex] \frac{5}{5} [/tex] = [tex] \frac{35}{20} [/tex]
[tex] \frac{7}{10} [/tex] × [tex] \frac{2}{2} [/tex] = [tex] \frac{14}{20} [/tex]
[tex] \frac{35}{20} - \frac{14}{20} = \frac{21}{20} [/tex]
21÷20=1.05 or [tex]1 \frac{1}{20} [/tex]
