-4 5/1 - 6 4/6=??? help!
yanalaym [24]

Answer:

-15 2/3.

Step-by-step explanation: First off, I performed the equation -4 5/1 - 6 4/6, yielding -15.6. I then translated that to a fraction. How to do that, you ask?

Example #1

Convert 0.32 to fraction:

0.32 = 32/100

Find the greatest common divisor (gcd) of the numerator and the denominator:

gcd(32,100) = 4

Reduce the fraction by dividing the numerator and the denominator with the gcd:

0.32 = (32/4) / (100/4) = 8/25

Example #2

Convert 2.56 to fraction:

2.56 = 2+56/100

Find the greatest common divisor (gcd) of the numerator and the denominator:

gcd(56,100) = 4

Reduce the fraction by dividing the numerator and the denominator with the gcd:

2+56/100 = 2 + (56/4) / (100/4) = 2+14/25  

In your problem the final answer would result in -15 2/3. Hope this answered your question.

Answer:

B

Step-by-step explanation:

|15-12|/4 = 3/4

|(-21+9)/8| = |-12/8| = 12/8 = 3/2 (Simply)

3/4 - 3/2 = -3/4

So the answer is B.
