There is no correct estimate because sqrt(28) is an irrational number and it is always possible to improve on an estimated value.
5^2 = 25
6^2 = 36 so the estimate is between 5 and 6.
5.25^2 = (5 1/4)^2 = (21/4)^2 = 441/16 = 27.5 so 5.25 is a better estimate.
Correct because 18+10 = 28
The factors of 28 are 1, 2, 4, 7, 14, and 28
You wouldn't have to estimate for addition, subtraction or multiplication. For division, use 30/5 = 6
28/38 * 100% = 73.68% You got about 74% on the test.
28 itself and multiples of 28
14/28 = 1/2 = 50%
It Equals 28. If You Do 7x4 It Will Say 28.
They are: 1, 2, 4, 7, 14 and 28
28, is the correct answer
31.8321
The estimate would be 9.3333 or 91/3
28/35 x 100 = 80%.
