Question

Write in ascending order:$-100,-4,-200,100,200,-150,20$

Answer 1

We know that positive integers lie to the right of zero on the number line and negative integers to the left of zero.

So positive integers are always greater than negative integers.

Now, let's compare positive integers first

$20,100,200$

$⟹20<100<200$ -----(1)

Now, let's compare negative integers

$-100,-4-200,-150$

We know that least negative number is the greatest among negative numbers

$⟹-200<-150<-100<-4$ -----(2)

Combining (1) and (2) we get,

$⟹-200<-150<-100<-4<20<100<200$
