Answer» ong>Answer: Step-by-step explanation: -13 by 20,6 by 15, 7 by 12, -9 by 10, 3 by 5
denominator terms are
20 , 15 , 12 ,10 & 5
We will find LCM of these NUMBERS first
20 = 5×2×2
15= 5×3
12 = 3×2×2
10=5×2
5 = 5
LCM = 5×3×2×2 = 60
lets multiply NUMERATOR and denominator to make denominator of each number = 60
ascending ORDER
-9/10 , -13/20 , 6/15 , 7/12 , 3/5
DESCENDING order will be
3/15 , 7/12 , 6/15 , - 13/20 , -9/10
