Question

tính nhanh :

5 3/5 + 1, 75 + 6 1/8 + 4 1/4 + 3,875 + 3,4

Answer 1

10,6+1,75+7,625+10,25+3,875+3,4

12,35+17,875+7,275

30,225+7,275

37,5

Answer 2

\(5\frac{3}{5}+1,75+6\frac{1}{8}+4\frac{1}{4}+3.875+3,4\)

\(=5,6+1,75+6,125+4,25+3,875+3,4\)

\(=\left(5,6+3,4\right)+\left(1,75+4,25\right)+\left(6,125+3,875\right)\)

\(=9+6+10\)

\(=25\)
