Evaluate the expression \( c-b \) when \( b=\frac{4}{5} \) and \( c=6 \). Write in simplest form.

To evaluate the expression \( c - b \) with the given values \( b = \frac{4}{5} \) and \( c = 6 \), follow these steps: 1. **Substitute the values into the expression:** \[ c - b = 6 - \frac{4}{5} \] 2. **Convert the whole number 6 to a fraction with the same denominator as \( \frac{4}{5} \) to facilitate subtraction:** \[ 6 = \frac{6 \times 5}{5} = \frac{30}{5} \] 3. **Subtract the fractions:** \[ \frac{30}{5} - \frac{4}{5} = \frac{30 - 4}{5} = \frac{26}{5} \] 4. **Simplify the fraction if necessary:** \[ \frac{26}{5} \text{ is already in its simplest form.} \] **Final Answer:** \[ c - b = \frac{26}{5} \]
