Step-by-step explanation:

Kristin has 3 2/3 yards of plaid ribbon. Converting 3 2/3 yards to improper fraction, it becomes 11/3 yards of plaid ribbon.

She has 2 5/6 yards of polka - dot ribbon. Converting 2 5/6 yards to improper fraction, it becomes 17/6 yards of polka - dot ribbon.

The total number of yards of ribbon that Kristin has would be

11/3 + 17/6 = (22 + 17)/6 = 39/6 yards of ribbon.

Converting to decimal, it becomes 6.5 yards of ribbon. Approximating 6.5 to the nearest yards, it becomes 7 yards. This is because the first digit after the decimal point is 5 and thus, can be rounded up

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!
