Answer

The estimated difference is approximately 0.233.

Solution

Calculate or simplify the expression \( 5/6-3/5 \). Calculate the value by following steps: - step0: Calculate: \(\frac{5}{6}-\frac{3}{5}\) - step1: Reduce fractions to a common denominator: \(\frac{5\times 5}{6\times 5}-\frac{3\times 6}{5\times 6}\) - step2: Multiply the numbers: \(\frac{5\times 5}{30}-\frac{3\times 6}{5\times 6}\) - step3: Multiply the numbers: \(\frac{5\times 5}{30}-\frac{3\times 6}{30}\) - step4: Transform the expression: \(\frac{5\times 5-3\times 6}{30}\) - step5: Multiply the numbers: \(\frac{25-3\times 6}{30}\) - step6: Multiply the numbers: \(\frac{25-18}{30}\) - step7: Subtract the numbers: \(\frac{7}{30}\) The estimated difference between \( \frac{5}{6} \) and \( \frac{3}{5} \) is approximately 0.233.

Bonus Knowledge

To estimate the difference \( \frac{5}{6} - \frac{3}{5} \), we can round each fraction to a simpler form. The fraction \( \frac{5}{6} \) is approximately \( 1 \) (since it's close to \( \frac{6}{6} \)), and \( \frac{3}{5} \) can be rounded to \( 0.5 \). So, estimating the difference gives us \( 1 - 0.5 = 0.5 \). Thus, a good estimate for \( \frac{5}{6} - \frac{3}{5} \) is around \( 0.5 \). For a more precise approach, find a common denominator, which is \( 30 \) in this case. Convert \( \frac{5}{6} \) to \( \frac{25}{30} \) and \( \frac{3}{5} \) to \( \frac{18}{30} \). Now, \( \frac{25}{30} - \frac{18}{30} = \frac{7}{30} \), which is about \( 0.23 \). Thus, the exact difference is \( \frac{7}{30} \), but our estimated difference of \( 0.5 \ gives you a quick idea!
