7. Add or Subtract P\&TY. \( -\frac{2}{7}-0.3+2 \)

Calculate or simplify the expression \( -\frac{2}{7}-0.3+2 \). Calculate the value by following steps: - step0: Calculate: \(-\frac{2}{7}-0.3+2\) - step1: Add the numbers: \(-\frac{2}{7}+1.7\) - step2: Convert the expressions: \(-\frac{2}{7}+\frac{17}{10}\) - step3: Reduce fractions to a common denominator: \(-\frac{2\times 10}{7\times 10}+\frac{17\times 7}{10\times 7}\) - step4: Multiply the numbers: \(-\frac{2\times 10}{70}+\frac{17\times 7}{10\times 7}\) - step5: Multiply the numbers: \(-\frac{2\times 10}{70}+\frac{17\times 7}{70}\) - step6: Transform the expression: \(\frac{-2\times 10+17\times 7}{70}\) - step7: Multiply the numbers: \(\frac{-20+17\times 7}{70}\) - step8: Multiply the numbers: \(\frac{-20+119}{70}\) - step9: Add the numbers: \(\frac{99}{70}\) The result of the expression \(-\frac{2}{7}-0.3+2\) is \(\frac{99}{70}\), which can also be written as \(1\frac{29}{70}\) or approximately \(1.4\dot{1}4285\dot{7}\).
