Mathematics
1 answer:
Step2247 [10]3 years ago
4 0
The second ratio can be simplified to the first by dividing every number by 9.
To simplify a ratio, divide all numbers by a common factor to get the simplest integer (whole number) ratio. You may need to multiply all the numbers in some cases if the given ratio has numbers below 1 (fractions).
The key idea is to maintain the proportion, i.e. you have to multiply or divide all the numbers, you cannot multiply or divide just one of them or the ratio will become disproportioned.

How many revolutions will a car wheel of diameter 22 in. make as the car travels a distance of one mile
Marianna [84]

It would be take upto 999 revolutions.

<em>Let try to solve it,</em>

Let n represent number of revolutions.

We are asked to find the number of revolutions it will take for a car wheel of diameter 30 in. to travel a distance of one mile.

1 mile = 63360 inches.

We will use circumference of circle formula to solve our given problem.

Circumference = pi*d , where, D represents diameter of circle.

Now, we will set the product of n and circumference of circle equal to 63360 inches as:

pi*22*n= 63360

n= 63360*7/ 22*22

n= 443520/444

n= 998.91

Therefore It would be take upto 999 revolutions.
