simplify (7xy)/(21xy^2)

simplify

\frac{7 x y}{21 x y ^{2}}

\frac{1}{3 y}

Solution steps

\frac{7 x y}{21 x y ^{2}}

Cancel the common factor:

x

= \frac{7 y}{21 y ^{2}}

Factor the number:

21 = 7 \cdot 3

= \frac{7 y}{7 \cdot 3 y ^{2}}

Cancel the common factor:

7

= \frac{y}{3 y ^{2}}

Simplify

\frac{y}{y ^{2}} : \frac{1}{y}

= \frac{1}{3 y}

132 = x^{2} + 9 x + 20

- h^{2} + 6 h \geq 13000

\frac{5 !}{2 !}

w x^{2} y - 9 w x y + 14 w y

3 x^{2} - 20 x + 25
