\frac{28}{45}

Solution steps

\frac{7}{9} \cdot \frac{4}{5}

Apply the fraction rule:

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

= \frac{7 \cdot 4}{9 \cdot 5}

Multiply the numbers:

7 \cdot 4 = 28

= \frac{28}{9 \cdot 5}

Multiply the numbers:

9 \cdot 5 = 45

= \frac{28}{45}

25 x^{2} + 25

2 a - (2 a - 3 b) - b

(5 m - 3)^{2}

- 2 (7 x + 1) - 5 (3 x^{2} + 3 x + 2)

\frac{4}{5} + \frac{9}{2}
