Arrange the following rational numbers in ascending order
a) 2/3 , 5/7 , -4/-9 , 1/4
b) 4/-9 , -5/12 , -7/18 , -2/3
Answers
Answer:
1/4 , 2/3 , -4/-8 , 5/7 is correct answer for a
Answer:
The Ascending orders of the given numbers are : -
a) 63 / 252 , 112 / 252 , 168 /252 , 180 / 252
b) 24 /36 , -16 / 36 , -15 / 36 , -14 / 256
Step-by-step explanation:
a) First, we need to find the LCM of the 4 denominators ( 3 , 7 , 9 , 4 )
LCM = 252
Multiply the numbers to get the denominators as 252.
The Numbers will be changed to 168 / 252 , 180 / 252 , 112 / 252 and 63 / 252.
The ascending order will be 63 / 252 , 112 / 252 , 168 /252 , 180 / 252
b) Similarly we have to find the LCM of the 4 denominators( 9 , 12 , 18 , 3) here as well.
LCM = 36
Multiply the numbers to get the denominators as 36.
The numbers will be changed to -16 / 36 , -15 / 12 , -14 / 256 , -24 / 36.
The ascending order will be -24 /36 , -16 / 36 , -15 / 36 , -14 / 256
