From different proportions with 9, 11, 27 and 33.

From different proportion with 5, 15, 10 and 30.

Let's prepare table as in from different proportion with 5,15, 10 and 30

From different proportions with 7, 8, 14, 16.

Let's find, if the following number are in proportion (b) 22, 11, 72, 36

Three elements X, Y and Z form three different compounds XY, YZ, and XZ. If XY contains 75% X, XZ contains 72.76% Z and YZ contains 11.11% Y, then show that these results illustrate the law of reciprocal proportion.

"Two different elements may combine together in a definite proportion by mass to form two different isomeric compounds. Again two different elements may combine together in different proportions by mass to produce two different compounds". Comment on this.
