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

swat32

Answer:

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

Step-by-step explanation:

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

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

$=\frac{17}{4}$

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

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

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

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

$=\frac{13}{4}+3$

$=\frac{25}{4}$

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

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