Answer:
[tex]5\frac{7}{20}[/tex]
Step-by-step explanation:
First see if both mixed numbers have the same common denominators.
[tex]9\frac{1}{10} -3\frac{3}{4}[/tex] different common denominators.
Find the LCM for both mixed numbers.
Answer: 20
10: 10, 20
4: 4, 8, 12, 16 and 20
Next convert each of the mixed numbers into a common denominator of 20.
[tex]9\frac{1}{10} =9\frac{2}{20}[/tex] [tex]3 \frac{3}{4} = 3\frac{15}{20}[/tex]
For [tex]9\frac{1}{10}[/tex] multiply the denominator by 2 to get a common denominator of 20. Whatever number you multiplied to the denominator, you multiply it to the numerator. Except the whole number of course.
Same thing goes to the other fraction! I'm running out of time :(
