the cost price, 450 of an article is reduced by 150, find the ratio by which the price is reduced

150 / 450 = 150 āˆ™ 1 / 150 āˆ™ 3 = 1 / 3

To find the ratio by which the price is reduced, we can use the formula:

Ratio = Amount of reduction / Original price

In this case, the amount of reduction is 150 and the original price is 450.

Ratio = 150 / 450

Simplifying the ratio:

Ratio = 1/3

Therefore, the price is reduced by a ratio of 1:3.

To find the ratio by which the price is reduced, we need to calculate the difference between the original price and the reduced price, and then express that as a ratio.

In this case, the original price (also known as the cost price) is $450, and it is reduced by $150.

To calculate the reduced price, we subtract the reduction amount from the original price:
Reduced Price = Cost Price - Reduction Amount
Reduced Price = $450 - $150
Reduced Price = $300

Now that we have the original price and the reduced price, we can calculate the ratio by which the price is reduced.

Ratio = Reduction Amount / Original Price
Ratio = $150 / $450
Ratio = 1/3

Therefore, the ratio by which the price is reduced is 1/3 or 1:3.
