To solve the problem, we need to subtract \(-1 \frac{2}{3}\) from \(5 \frac{1}{2}\).
First, convert the mixed numbers to improper fractions:
1. Convert \(5 \frac{1}{2}\):
\[
5 \frac{1}{2} = 5 \times 2 + 1 = 10 + 1 = \frac{11}{2}
\]
2. Convert \(-1 \frac{2}{3}\):
\[
-1 \frac{2}{3} = -\left(1 \times 3 + 2\right) = -\frac{5}{3}
\]
Now we rewrite the subtraction:
\[
5 \frac{1}{2} - \left(-1 \frac{2}{3}\right) = \frac{11}{2} + \frac{5}{3}
\]
Next, we need a common denominator to add these two fractions. The least common multiple of \(2\) and \(3\) is \(6\).
Convert each fraction:
\[
\frac{11}{2} = \frac{11 \times 3}{2 \times 3} = \frac{33}{6}
\]
\[
\frac{5}{3} = \frac{5 \times 2}{3 \times 2} = \frac{10}{6}
\]
Now we can add the two fractions:
\[
\frac{33}{6} + \frac{10}{6} = \frac{33 + 10}{6} = \frac{43}{6}
\]
Next, convert \(\frac{43}{6}\) back to a mixed number:
\[
\frac{43}{6} = 7 \frac{1}{6}
\]
Now we analyze our result \(7 \frac{1}{6}\):
- It is greater than 4.
Therefore, the result of subtracting \(-1 \frac{2}{3}\) from \(5 \frac{1}{2}\) is **greater than 4**.
