\frac{414}{7} + 40 : \frac{694}{7}

\frac{414}{7} + 40

\frac{414}{7} + 40 = \frac{694}{7}

\frac{414}{7} + 40

Convert element to fraction:

40 = \frac{40 \cdot 7}{7}

= \frac{40 \cdot 7}{7} + \frac{414}{7}

Since the denominators are equal, combine the fractions:

\frac{a}{c} \pm \frac{b}{c} = \frac{a \pm b}{c}

= \frac{40 \cdot 7 + 414}{7}

40 \cdot 7 + 414 = 694

40 \cdot 7 + 414
