Solve this r/6=5 2/3
myrzilka [38]
First, incorporate the 5 into the 2/3 fraction by multiplying the 5 by the 3 and then adding that quantity by the 2, which now makes the fraction:
17/3
Now set it up with the equation:
r/6 = 17/3
r/6×3 = 17/3×3
r/3 = 17
r/3×3 = 17×3
r = 51

8,|3 |,-5,| -2 |,-2
Ronch [10]
When a number has the |absolute value|, it refers to the amount of units the number is from 0. (you can think of a timeline)
|3| is 3 units away from zero
|-5| is 5. it is NOT -5 units from 0, since a number cannot be -5 units away.
Basically, these lines | x | will make the number positive.




answer
-5,-2, | -2 |, | 3 |, 8
