Proportion Word Problem Worksheets
How to Determine a Proportion?
In mathematical form a proportion flows in this manner = : :
We place this sign among two ratios for example, 16:24 : : 20:30 > (a)
What does the proportion exactly mean?
If you have two equivalent ratios, it means they are in proportion.
Is the equation (a) in proportion or not?
For R.H.S; 16/24 (simplify form), both comes in table of 2. The value will be 16/24 = 8/12 and again use 2 for division like this 8/12 = 4/6 and again, you will divide it by the table of 2 and the answer will be 2/3.
16:24 = 2:3. For L.H.S; 20:30 = 20/30 = 2/3. The ratio will be 2:3.
R.H.S = L.H.S:
16:24 : : 20: 30
2:3 2:3
Hence, these ratios are equivalent, and that is why it will be correct if we say they both ratios are in proportion.
