$$(2\frac{2}{5}+3\frac{1}{4}-2\frac{7}{8})\times?=222$$

Solution

Expression : $$(2\frac{2}{5}+3\frac{1}{4}-2\frac{7}{8})\times?=222$$

=> $$[(2 + 3 - 2) + (\frac{2}{5} + \frac{1}{4} - \frac{7}{8}) \times x] = 222$$

=> $$(3 + \frac{2}{5} - \frac{5}{8}) \times x = 222$$

=> $$(3 - \frac{9}{40}) \times x = 222$$

=> $$\frac{111}{40} x = 222$$

=> $$x = 222 \times \frac{40}{111}$$

=> $$x = 2 \times 40 = 80$$
