To compare fractions you need a common denominator, then you can make a comparison. You would divide the number line between 0 and 1 (or any 2 whole numbers on the number line) based on that common denominator. For example... if you were trying to compare 3/4 and 2/8, you would find the common denominator (in this case 8) and convert the fractions...
3/4 = 6/8
2/8 stays as 2/8
Now you would go to the number line between 0 and 1 and divide it into 8 equal pieces. 3/4 would go over the 6th division and 2/8 would go over the second division.
That would give you a good visual that 2/8 < 3/4
[ / / / / / / / ]
0 2/8 3/4 1

Step-by-step explanation:
100 lbs = 1 lb of melon 99 lb water
Let "x" be weight of water:
percentage = weight of water / (1 lb melon + water)
.98 = x / (1 lb melon + x)
.98 = x / 1 +x
.98 + .98x = x
.98 = .02x
x = 49
49 lbs of water
1 lb melon + 49 lbs water = 50 lbs total
49 / 50 = 98%
Therefore, 50 POUNDS of water evaporated
