Answer: biggest no.=27. Smallest number=9
Step-by-step explanation:
Let's take the smallest number as x and the biggest number as 3x since it is 3 times bigger than x.
The sum of these two numbers is 36
3x+x=36
4x=36
X( smallest number)=36/4: 9
While, the biggest number is 3x: 3×9=27
I hope this helps you
x+0,2x=1-0,7
1,2x=0,3
x=0,3/1,2
x=1/4
x=0,25
