Question

\(\frac{4,5:\left[47,375-\left(26\frac{1}{3}-18.0,75\right).2,4:0,88\right]}{17,81:1,37-23\frac{2}{3}:1\frac{5}{6}}\)

Answer 1

Đặt A:

A = \(\frac{4,5:47,375-\left(26\frac{1}{3}-18.0,75\right).2,4:0,88}{17,81:1,37-23\frac{2}{3}:1\frac{5}{6}}\)

= \(\frac{\frac{9}{2}:\left[\frac{379}{8}-\left(\frac{79}{3}-\frac{27}{2}\right).\frac{30}{11}\right]}{13-\frac{71}{3}.\frac{6}{11}}\)

= \(\frac{\frac{9}{2}:\left[\frac{379}{8}-\frac{77}{6}.\frac{30}{11}\right]}{13-\frac{142}{11}}\)

= \(\frac{\frac{9}{2}:\left[\frac{379}{8}-35\right]}{\frac{1}{11}}\)

= \(\left(\frac{9}{2}:\frac{99}{8}\right).1\)

= \(\frac{4}{11}.11\) = 4

=> A = 4
