The answer is 2 19/50.
First of all you have to convert the mixed numbers into improper fractions. So, 1 2/5 is equal to 7/5 and 1 7/10 is equal to 17/10. Next you multiply the denominators by the denominators and multiply the numerator by the numerator. 7 times 17 is 119 and 5 times 10 is 50. So the fraction is 119/50. You convert the improper fraction into a mixed number, which is 2 19/50.
