Answer
is the product rational or irrational
Answered by GPT 3.5
To simplify the expression 10yz/-2z, we can cancel out the common factor z in the numerator and denominator:

10yz / -2z = 10y/-2 = -5y

To multiply 7.56 by 6.7 (repetitive), we can write 6.7 (repetitive) as a fraction:

6.7 (repetitive) = 6.7777...

Now we can multiply:

7.56 * 6.7 (repetitive) = 7.56 * 6.7777...

To bring the repeating decimal into a proper fraction, we'll use the variables x and y:

x = 6.7777...
10x = 67.7777...
10x - x = 67.7777... - 6.7777...
9x = 61

Now we can solve for x:

x = 61 / 9
x = 6.7777...

Now we can substitute this value back into the original multiplication:

7.56 * 6.7 (repetitive) = 7.56 * 6.7777... = 51.2772...

Therefore, the result is approximately 51.2772.
