This depends on how accurate an estimate is required. If your answer need only be whole numbers, then 0.69 is slightly larger than 2/3 which is 0.66 = you could estimate 14 - which is 2/3 of 21. -- Alternatively, if your answer ought to be to one decimal place then you could say that it is nearly 70% and multiply 21 by 0.7 and get 14.7

When we use a least-squares line to predict y values for x values beyond the range of x values found in the data are we extrapolating or interpolating?
If you're estimating a point OUTSIDE the data range, it's extrapolating. If you're estimating a point WITHIN the data range, it's interpolating.

What is the ratio of the sum of two numbers whose product is 21 to their difference?
Two specific cases of pairs of numbers whose product is 21 are: 1 x 21 and 3 x 7. The ratio of their sum to their difference is: 1 x 21 ... (21+1):(21 - 1) = 22:20 = 11 : 10, and 3 x 7 ... (3+7):(7-3) = 10:4 = 5 : 2. To find a general formula, let the larger number be x and the smaller be 21/x. Their sum is x + 21/x = (x^2 +21)/x Their difference is x - 21/x = (x^2 -21)/x Ratio of sum to difference is [(x^2+21)/x] / [(x^2-21)/x] = [(x^2+21)/x] * [x/(x^2-21)] = (x^2+21)/(x^2-21) Check: This formula produces the results found above.
