1. Problem Description

We need to solve the subtraction problem 10345\frac{10}{3} - \frac{4}{5} by finding a common denominator and simplifying the resulting fraction. The common denominator is given as
1
5.

2. Solution Steps

First, we convert both fractions to have a common denominator of
1

5. To convert $\frac{10}{3}$ to a fraction with denominator 15, we multiply both the numerator and the denominator by 5:

103=10×53×5=5015\frac{10}{3} = \frac{10 \times 5}{3 \times 5} = \frac{50}{15}
To convert 45\frac{4}{5} to a fraction with denominator 15, we multiply both the numerator and the denominator by 3:
45=4×35×3=1215\frac{4}{5} = \frac{4 \times 3}{5 \times 3} = \frac{12}{15}
Now we can subtract the fractions:
50151215=501215=3815\frac{50}{15} - \frac{12}{15} = \frac{50 - 12}{15} = \frac{38}{15}
The fraction 3815\frac{38}{15} is already in simplest form. We can also convert this improper fraction to a mixed number. 38÷15=238 \div 15 = 2 with a remainder of

8. So, $\frac{38}{15} = 2\frac{8}{15}$.

3. Final Answer

10345=50151215=3815=2815\frac{10}{3} - \frac{4}{5} = \frac{50}{15} - \frac{12}{15} = \frac{38}{15} = 2 \frac{8}{15}
The boxes should be filled in as follows:
