Take as long as you need in not in a hurry (25pst) translate the following sentence into math symbols. then solve the problem. y more than 4 is –36 how would you convince a fellow student that the number 0.57 is a rational number?

4+y = -36

y = -40

The definition of a rational number is the ratio of two integers

Lets rewrite .57 as a fraction

.57 = 57/100

Both 57 and 100 are integers and 57/100 is the ratio of integers so .57 is rational.

Step-by-step explanation:

4+y = -36

Subtract 4 from each side

4+y-4 = -36-4

y = -40

The definition of a rational number is the ratio of two integers

Lets rewrite .57 as a fraction

.57 = 57/100

Both 57 and 100 are integers and 57/100 is the ratio of integers so .57 is rational.
