` @Answer`
Ta có :
`3/5=(3xx24)/(5xx24)=72/120`
`7/3=(7xx40)/(3xx40)= 280/120`
`6/8=(6xx15)/(8xx15)=90/120`
`5/3=(5xx40)/(3xx40)=200/120`
`-` Thứ tự từ bé đến lớn là :
`->3/5 ;6/8 ; 5/3; 7/3`
3/5<3/4=6/8
5/3<7/3
=>3/5<6/8<5/3<7/3
\(\dfrac{3}{5},\dfrac{7}{3},\dfrac{6}{8},\dfrac{5}{3}\)
msc:120
\(\dfrac{3}{5}=\dfrac{72}{120}\)
\(\dfrac{7}{3}=\dfrac{280}{120}\)
\(\dfrac{6}{8}=\dfrac{90}{120}\)
\(\dfrac{5}{3}=\dfrac{200}{120}\)
do \(\dfrac{72}{120}< \dfrac{90}{120}< \dfrac{200}{120}< \dfrac{280}{120}\)
=>\(\dfrac{3}{5}>\dfrac{6}{8}>\dfrac{5}{3}>\dfrac{7}{3}\)
=> theo thứ tự từ bé đến lớn :\(\dfrac{3}{5},\dfrac{6}{8},\dfrac{5}{3},\dfrac{7}{3}\)
