Question

30,75+1/12+3-1/6

Answer 1

giúp mình với các bạn ơi

Answer 2

3075/100+1/12+3-1/6

=123/4₍₃₎+1/12(1)+3₍₁₂₎+1/6(2)

=369/12+1/12+36/12+2/12

369+1+36+2

12 

=408/12=34

Answer 3

\(30,75+\frac{1}{12}+3-\frac{1}{6}\)

\(=\frac{3075}{100}+\frac{1}{12}+\frac{3}{1}-\frac{1}{6}\)

\(=\frac{123}{4}+\frac{1}{12}+\frac{3}{1}-\frac{1}{6}\)

\(=\frac{369}{12}+\frac{1}{12}+\frac{36}{12}-\frac{2}{12}\)

\(=\frac{369+1+36-2}{12}\)

\(=\frac{404}{12}=\frac{101}{3}\)
