2.3 Properties of Ratios - II

Express the terms of a ratio as natural numbers.

If the antecedent or consequent or both are fractions, find the L.C.M. of the denominators of the fractions and multiply both terms of the ratio by this L.C.M. This will convert fractional terms into natural numbers.

Examples:
Change the terms of the ratio 1/2:1/3 to natural numbers.
The L.C.M. of the denominators 2 and 3 is 6.
1/2:1/3 = (1/2)x6 : (1/3)x6 = 3:2

Directions: Change the terms of the ratios to natural numbers. Also write at least ten examples of your own.
