This could be solved as a group of mixed numbers, but I like to work with improper fractions more. 17/4 - 51/20 Next, you need to find a common denominator. 85/20 -51/20 When adding and subtracting fractions, you only work in the numerator, and the denominator stays the same. 34/20 Then, you just simplify. Improper fraction: 17/10 Mixed number: 1 7/10 Decimal: 1.7
