化简 (66c+99d)*1/3

解答

化简

(66 c + 99 d) \cdot \frac{1}{3}

22 c + 33 d

求解步骤

(66 c + 99 d) \frac{1}{3}

= \frac{1}{3} (66 c + 99 d)

使用分配律:

a (b + c) = ab + a c

\frac{1}{3} (66 c + 99 d) = \frac{1}{3} \cdot 66 c + \frac{1}{3} \cdot 99 d

= \frac{1}{3} \cdot 66 c + \frac{1}{3} \cdot 99 d

化简

\frac{1}{3} \cdot 66 c + \frac{1}{3} \cdot 99 d : 22 c + 33 d

= 22 c + 33 d
