\(a\times1\dfrac{1}{3}+a\times2\dfrac{2}{3}+a\times6=110\)
\(a\times\left(1\dfrac{1}{3}+2\dfrac{2}{3}+6\right)=110\)
\(a\times\left(1+\dfrac{1}{3}+2+\dfrac{2}{3}+6\right)=110\)
\(a\times\left(9+\dfrac{1}{3}+\dfrac{2}{3}\right)=110\)
\(a\times10=110\)
\(a=110:10\)
\(a=11\)
Vậy: a = 11
\(a\times1\dfrac{1}{3}+a\times2\dfrac{2}{3}+a\times6=110\)
\(a\times\left(1\dfrac{1}{3}+2\dfrac{2}{3}+6\right)=110\)
\(a\times\left(1+\dfrac{1}{3}+2+\dfrac{2}{3}+6\right)=110\)
\(a\times\left[\left(1+2+6\right)+\left(\dfrac{1}{3}+\dfrac{2}{3}\right)\right]=110\)
\(a\times\left(9+1\right)=110\)
\(a\times10=110\)
\(a=110:10\)
\(a=11\)
`#3107.101107`
$a \times 1\dfrac{1}{3} + a \times 2\dfrac{2}{3} + a \times 6 = 110$
$a \times (1 \dfrac{1}{3} + 2\dfrac{2}{3} + 6) = 110$
$ a \times 10 = 110$
$a = 110 \div 10$
$a = 11$
Vậy, `a = 11.`
