Question

$\frac{ - 10}{3} \frac{12}{5} \frac{ - 2}{7} \frac{9}{2} arrange \: in \: descending \: order$
​

Answer 1

Answer:

$\frac{9}{2}$,$\frac{12}{5}$,$\frac{-2}{7}$,$\frac{-10}{3}$  

Step-by-step explanation:

LCM = 210

$\frac{-10}{3}$ *$\frac{70}{y70}$ =$\frac{-700}{210}$

$\frac{12}{5}$ *$\frac{42}{42}$=$\frac{504}{210}$

$\frac{-2}{7}$*$\frac{30}{30}$ =$\frac{-60}{210}$

$\frac{9}{2}$*$\frac{105}{105}$=$\frac{945}{210}$

Descending order = $\frac{945}{210}$   ,$\frac{504}{210}$,$\frac{-60}{210}$,$\frac{-700}{210}$    

In other words,

$\frac{9}{2}$,$\frac{12}{5}$,$\frac{-2}{7}$,$\frac{-10}{3}$
