Question

arrange in descending order 2/5,7/4,5/6,5/8​

Answer 1

Answer:

FIRST STEP ( FINDING THE LCM )

WE WILL TAKE LCM OF 5 , 4 , 6 , 8 ( DENOMINATORS )

LCM = 2 | 5 , 4 , 6 , 8

2 | 5 , 2 , 3 , 4

| 5 , 1 , 3 , 2

LCM = 2 × 2 × 5 × 2 × 3

= 4 × 10 × 3

= 4 × 30

= 120

SECOND STEP ( MAKING THE DENOMINATOR SAME )

2 = 2 × 24 = 16

5 = 5 × 24 = 120

7 = 7 × 30 = 210

4 = 4 × 30 = 120

5 = 5 × 20 = 100

6 = 6 × 20 = 120

5 = 5 × 15 = 75

8 = 8 × 15 = 120

THIRD STEP ( WRITING THE FRACTIONS IN DESCENDING ORDER ) ( FROM BIGGER TO SMALLER )

THEREFORE ,

DESCENDING ORDER

= 210 , 100 , 75 , 160

120 120 120 120

OR ,

= 7 , 5 , 5 , 2

4 6 8 5

FOR KNOWLEDGE ,

ASCENDING ORDER ( FROM SMALLER TO BIGGER )
