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
Hence, these ratios are equivalent, and that is why it will be correct if we say they both ratios are in proportion.
Uses slightly larger sentences and numbers than the basic lesson. Example: A child can run at a rate of 4 1/2 blocks per minutes. How long does it take the child to run 9 blocks? The child run at rate 4 1/2 block per minutes. The child can run for 9 blocks in 9 / (4 1/2 ) = 2 The child run 9 blocks in 2 minutes.View worksheet
