Answer

The answer is \(2\frac{4}{15}\).

Solution

Calculate or simplify the expression \( 7\frac{3}{5}-5\frac{1}{3} \). Calculate the value by following steps: - step0: Calculate: \(7\frac{3}{5}-5\frac{1}{3}\) - step1: Convert the expressions: \(\frac{38}{5}-\frac{16}{3}\) - step2: Reduce fractions to a common denominator: \(\frac{38\times 3}{5\times 3}-\frac{16\times 5}{3\times 5}\) - step3: Multiply the numbers: \(\frac{38\times 3}{15}-\frac{16\times 5}{3\times 5}\) - step4: Multiply the numbers: \(\frac{38\times 3}{15}-\frac{16\times 5}{15}\) - step5: Transform the expression: \(\frac{38\times 3-16\times 5}{15}\) - step6: Multiply the numbers: \(\frac{114-16\times 5}{15}\) - step7: Multiply the numbers: \(\frac{114-80}{15}\) - step8: Subtract the numbers: \(\frac{34}{15}\) The result of subtracting \(7\frac{3}{5}\) from \(5\frac{1}{3}\) is \(2\frac{4}{15}\) or \(2.2\dot{6}\) in mixed number form.

To solve the subtraction \( 7 \frac{3}{5} - 5 \frac{1}{3} \), we first convert both mixed numbers to improper fractions. For \( 7 \frac{3}{5} \): \[ 7 \times 5 + 3 = 35 + 3 = 38, \text{ so } 7 \frac{3}{5} = \frac{38}{5}. \] For \( 5 \frac{1}{3} \): \[ 5 \times 3 + 1 = 15 + 1 = 16, \text{ so } 5 \frac{1}{3} = \frac{16}{3}. \] Next, we find a common denominator for the fractions, which is 15. We convert both fractions: \[ \frac{38}{5} = \frac{38 \times 3}{5 \times 3} = \frac{114}{15}, \] \[ \frac{16}{3} = \frac{16 \times 5}{3 \times 5} = \frac{80}{15}. \] Now, we perform the subtraction: \[ \frac{114}{15} - \frac{80}{15} = \frac{114 - 80}{15} = \frac{34}{15}. \] Now, we convert \(\frac{34}{15}\) to a mixed number. Divide 34 by 15: - 15 goes into 34 twice (2), leaving a remainder of \(34 - 30 = 4\). Thus, \( \frac{34}{15} = 2 \frac{4}{15} \). The final answer is: \[ 2 \frac{4}{15}. \]
