Question

The Sacramento City Council adopted a law to reduce the allowed sound intensity level of the much-despised leaf blowers from their current level of about 92 dB to 67 dB. With the new law, what is the ratio of the new allowed intensity to the previously allowed intensity?

Answer 1

With the new law, the ratio of new allowed intensity to previously allowed intensity is
`(67)/(92) = 0.7283` or

67:92

Step-by-step explanation:

Let's start explaining that a ratio is a mathematics expression to compare two or more numbers.

From the question suppose that:

X = new allowed intensity

Y = previously allowed intensity

The most simple ratio, compare two numbers. A ratio is commonly expressed using the next expressions:

X to Y

X : Y

`(X)/(Y)`

From there you can say that the ratio of the new allowed intensity to the previously allowed intensity is

`(67)/(92) = 0.7283` or

67:92

Note: the first number in the sentence should be located first. For instance, a ratio of 4 red apples to 5 green apples is 4:5 or 4 to 5, not 5:4 or 5 to 4.
