Solution steps

\frac{1}{2} \cdot 9 \cdot 7

Convert element to fraction:

9 = \frac{9}{1}

= \frac{1}{2} \cdot \frac{9}{1} \cdot 7

Convert element to fraction:

7 = \frac{7}{1}

= \frac{1}{2} \cdot \frac{9}{1} \cdot \frac{7}{1}

Apply the fraction rule:

\frac{a}{b} \cdot \frac{c}{d} = \frac{a \cdot c}{b \cdot d}

= \frac{1 \cdot 9 \cdot 7}{2 \cdot 1 \cdot 1}

Multiply the numbers:

1 \cdot 9 \cdot 7 = 63

= \frac{63}{2 \cdot 1 \cdot 1}

Multiply the numbers:

2 \cdot 1 \cdot 1 = 2

= \frac{63}{2}

a (x - 1) - (a + 2) (x - 1)

(3)^{2} + (5)^{2}

\frac{2}{x} - \frac{4}{x + 4}

2 \frac{3}{10}

(a - b)^{2} - (c - d)^{2}
