Question

(3,8×1,75:0,95):2,3+0,4=​

Answer 1

$\frac{3.8 \times \frac{1.75}{0.95} }{2.3} + 0.4 = \frac{3.8 \times \frac{0.35}{0.19} }{2.3} + 0.4 = \\ = \frac{20 \times 0.35}{2.3} + 0.4 = \frac{7}{2.3} + 0.4 = \\ = \frac{70}{23} + \frac{4}{10} = \frac{700 + 92}{230} = \frac{396}{115} = 3 \frac{51}{115}$
