Answer:
Hey dear your answer is here:-
2/5,7/10,8/15, 13/30
LCM of 5,10,15,30= 180
2/5*36/36= 72/180
7/10* 18/18= 126/180
8/15* 12/12= 96/180
13/30= 6/6= 78/180
72/180; 126/180 ; 96/180; 78/180
ascending order:- 72/180;78/180;96/180;126/180 or
2/5; 13/30; 8/15; 7/10

Answer:
Step-by-step explanation:
The descending order of :
(i) 6/12 , -7/3 , 5/-12 , 11/-18
Step 1 = First convert the fractions into its standard form
= 6/12 (already in its standard form)
= -7/3 (already in its standard form)
= 5/-12 = -5/12
= 11/-18 = -11/18
Step 2 = find the lcm of 12 , 3 and 18
=lcm of 12 , 3 and 18 = 3 * 3 * 2 * 4
= 72
Step 3 = make the denominators same using the lcm
= 6*6/12*6 = 36/72
= -7*24/3*24 = -168/72
= -5*6/12*6 = -30/72
= -11*4/18*4 = -44/72
Step 4 = arrange in descending order
= 36/72 , -30/72 , -44/72 , -168/72
= 6/12 , -7/3 , -5/12 , -11/18
(ii)3/-16 , -6/8 , 3/8 , -15/24
Step 1 = First convert the fractions into its standard form
= 3/-16 = -3/16
= -6/8 (already in its standard form)
= 3/8 (already in its standard form)
= -15/24 (already in its standard form)
Step 2 = find the lcm of 16 , 8 and 24
=lcm of 16 , 8 and 24 = 2 * 2 * 2 * 2 * 3
= 48
Step 3 = make the denominators same using the lcm
= -3*3/16*3 = -9/48
= -6*6/8*6 = -36/48
= 3*6/8*6 = 18/48
= -15*2/24*2 = -30/48
Step 4 = arrange in descending order
= 18/48 , -9/48 , -30/48 , -36/48
= 3/8 , -3/16 , -15/24 , -6/8
