Answer:
13/36.
Step-by-step explanation:
First convert to improper fractions:
10 1/9 = (10*9 + 1)/9 = 91/9.
9 3/4 = (9*4 + 3)/4 = 39/4.
Next find the Lowest Common Denominator of 9 and 4.
This is 9*4 = 36.
Now convert both fractions to 36th:
For 91/9 we multiply by 4/4 and for 39/9 we multiply by 9/9
91*4 / 9*4 = 364/36 and 39*9 / 9*4 = 351/36, so we have:
364/36 - 351/36
= 13/36
