Show that the number –0.88 is a rational number by finding a ratio of two integers equal to the number.

This can be done with how you read decimals in place value (tenths, hundredths, thousandths, and so forth).

Our number is -0.88, which has 8 in the tens and hundredths place, or, 88 hundredths.

Write the hundredths part as the denominator, the first part as your numerator.

= -88 / 100

That satisfies the definition of a rational number, because both -88 and 100 are integers and we have a ratio between them. Further, we are not dividing by zero.

step-by-step explanation:

polynomial long division :

3.2     polynomial long division

dividing :   x4+5x3-4x2-8x+6

                              ("dividend")

by         :     x-1     ("divisor")

dividend     x4   +   5x3   -   4x2   -   8x   +   6

- divisor   * x3     x4   -   x3            

remainder         6x3   -   4x2   -   8x   +   6

- divisor   * 6x2         6x3   -   6x2        

remainder             2x2   -   8x   +   6

- divisor   * 2x1             2x2   -   2x    

remainder               -   6x   +   6

- divisor   * -6x0               -   6x   +   6

remainder                     0

quotient :   x3+6x2+2x-6   remainder:   0

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
