Question

3/5.8 +11/8.19 + 16/19.35 

Answer 1

\(\frac{3}{5.8}+\frac{11}{8.19}+\frac{16}{19.35}=\frac{1}{5}-\frac{1}{8}+\frac{1}{8}-\frac{1}{19}+\frac{1}{19}-\frac{1}{35}=\frac{1}{5}-\frac{1}{35}=\frac{6}{35}\)

Answer 2

Ta có: 3/5.8 + 11/8.19 + 16/19.35

= (1/5 - 1/8 ) + (1/8 - 1/19) + (1/19 - 1/35)

=1/5 - 1/35

=6/35

Answer 3

Ta có 3/5.8 +11/8.19 +16/19/35

=1/5 -1/8+1/8-1/19+1/19-1/35

=1/5-1/35

=6/35
