simplify (4z)/x*(5x)/(2a)

simplify

\frac{4 z}{x} \cdot \frac{5 x}{2 a}

\frac{10 z}{a}

Solution steps

\frac{4 z}{x} \cdot \frac{5 x}{2 a}

Apply the fraction rule:

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

= \frac{4 z \cdot 5 x}{x \cdot 2 a}

Cancel the common factor:

x

= \frac{4 z \cdot 5}{2 a}

Factor the number:

4 = 2 \cdot 2

= \frac{2 \cdot 2 z \cdot 5}{2 a}

Cancel the common factor:

2

= \frac{2 z \cdot 5}{a}

Multiply the numbers:

2 \cdot 5 = 10

= \frac{10 z}{a}

- 7.5 a \geq 15

2 (x + 4) = 4 \cdot 2 (x - 2) - 2 x

36 c^{2} - 49

- 7.5 x + 0.44 = - 5.56

(\frac{27}{8})^{- \frac{1}{3}}
