Evaluate the expression: \(-6.23 + -2.51 - 4.78\)

MathBot Answer:

\[-6.23 + -2.51 - 4.78 = - \frac{338}{25} = -13.52\]


\[\begin{aligned}-6.23 + -2.51 - 4.78& = - \left(6 + \frac{23}{100}\right) - \left(2 + \frac{51}{100}\right) - \left(4 + \frac{78}{100}\right)\\& = - \frac{623}{100} - \left(2 + \frac{51}{100}\right) - \left(4 + \frac{78}{100}\right)\\& = - \frac{623}{100} - \frac{251}{100} - \left(4 + \frac{78}{100}\right)\\& = - \frac{623}{100} - \frac{251}{100} - \left(4 + \frac{39}{50}\right)\\& = - \frac{623}{100} - \frac{251}{100} - \frac{239}{50}\\& = - \frac{437}{50} - \frac{239}{50}\\& = - \frac{338}{25}\end{aligned}\]
