Question

The four sides of a garden are 14 1/2 feet, 31 2/3 feet, 28 1/3 feet, and 22 1/2 feet. How many feet of fencing are needed to go around the garden? First estimate the answer. Then solve for the exact answer.

Answer 1

For estimating, I would round to the nearest foot:
14 1/2 → 14
31 2/3 → 32
28 1/3 → 28
22 1/2 → 23

Estimate sum = 14+32+28+23 = 97 feet

Answer 2

For the exact answer, I would start by adding up the whole number parts:
14 + 31 + 28 + 22 = 95
Then find the LCD on the fraction parts (= 2×3 = 6) and convert to common denominators and add:
3/6 + 4/6 + 2/6 + 3/6 = 12/6 = 2

And add the whole number part and the fraction part:
95 + 2 = 97 feet.

Answer 3

so i put 97 for the estimated and 97 for the exact answer

Answer 4

Yes. There are different ways to estimate though (rounding to the nearest 5 or 10), so you could get a different estimation.
