Enter the value of 4 1/4 - 5/7 + (-2/7) - (-3)
swat32

Answer:

=6\frac{1}{4}

Step-by-step explanation:

4\frac{1}{4}-\frac{5}{7}+\left(-\frac{2}{7}\right)-\left(-3\right)

4\frac{1}{4}=\frac{4\cdot 4+1}{4}

=\frac{17}{4}

=\frac{17}{4}-\frac{5}{7}+\left(-\frac{2}{7}\right)-\left(-3\right)

=\frac{99}{28}+\left(-\frac{2}{7}\right)-\left(-3\right)

=\frac{99}{28}-\frac{2}{7}-\left(-3\right)

=\frac{13}{4}-\left(-3\right)

=\frac{13}{4}+3

=\frac{25}{4}

\frac{25}{4}=6\frac{1}{4}

=6\frac{1}{4}
