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

\(4\frac{1}{4} - 2\frac{11}{20}\)
Change them into improper fractions by multiplying the denominator(bottom) by the whole number then adding the numerator
\(\frac{17}{4}\) - \(\frac{51}{20}\)
You must have a common denominator
Multiply \(\frac{17}{4}\) by \(\frac{5}{5}\)⇒\(\frac{85}{20}\)
\(\frac{85}{20}\)-\(\frac{51}{20}\)=\(\frac{34}{20}\)
Simplify by dividing the numerator by the denominator
34÷20=\(1\frac{14}{20}\)⇒\(1 \frac{7}{10}\) reduced
You answer is \(1 \frac{7}{10}\)
