Question

arrange 5/8 3/16 1/4 and 17/32 in the descending order of their magnitudes. also find the sum of the lowest and the largest of these rational numbers. express the result obtained as a decimal fraction correct two decimal places​

Answer 1

Step-by-step explanation:

LCM of 8, 4, 16 ,32 = 32

5/8 = (5/8)*(4/4) = 20/32

3/16 = (3/16)*(2/2)= 6/32

1/4 = (1/4)*(8/8)= 8/32

17/32 = (17/32)*(1/1) = 17/32

descending order =

20/32, 17/32, 8/32, 6/32

5/8, 17/32, 1/4, 3/16

sum of 5/8+3/16

= 20/32+6/32= 26/32

= 0.81

Answer 2

Answer:

5/8 3/16 1/4 17/32

5×4/8×4= 20/32

3×2/16×2=6/32

1×8/4×8= 8/32

17/32

20/32, 17/32, 8/32, 6/32.

5/8 17/32 1/4 3/16

6/32+20/32 =6+20/32 =26/32

26/32 =0.8125
