tính nhanh

2/8 * 3/12 + 4/16 * 6/24

Answer 1

=1/4 x 1/4 + 1/4 x 1/4 ( rút gọn)

= 1/16 + 1/16

= 2/16 

k mk nha . cảm ơn bạn nhìu

Answer 2

=1/4x1/4+1/4x1/4

=(1/4+1/4)x1/4

=1/2x1/4

=1/8

Answer 3

\(\frac{2}{8}.\frac{3}{12}+\frac{4}{16}.\frac{6}{24}\)

\(=\frac{2}{8}.\frac{3}{12}+\frac{4}{16}.\frac{3}{12}\)

\(=\frac{3}{12}.\left(\frac{2}{8}+\frac{4}{16}\right)\)

\(=\)\(\frac{3}{12}.\frac{1}{2}\)

\(\frac{1}{8}\)

Answer 4

\(\frac{2}{8}x\frac{3}{12}=\frac{1}{16}+\frac{4}{16}x\frac{6}{24}=\frac{1}{8}\)

Answer 5

1/8 nhé
