Answer:

28.87

Explanation:

Given the expression 28 × 0.64, we are to find the best estimate;

28 × 0.64 = 28 × 64/100

28 × 64/100 = 28 * 16/25

28 * 16/25 = (28*16)/15

(28*16)/15 = 448/15

448/15 = 28.866666667

To get the best estimate, we will round it up to 2 decimal places

448/15 = 28.87

Hence the best estimate is 28.87
