Question

(9 x 10) + (3 x 1) + (7 x 0,1) + (6 x 0,01) = .....

Answer 1

(93, 95)

Explanation:

Simplify the following:

9×10 + 3×1 + (7×0, 1) + (6×0, 1)

0×7 = 0:

9×10 + 3×1 + (0, 1) + (6×0, 1)

0×6 = 0:

9×10 + 3×1 + (0, 1) + (0, 1)

9×10 = 90:

90 + 3×1 + (0, 1) + (0, 1)

3×1 = 3:

90 + 3 + (0, 1) + (0, 1)

90 + 3 + (0, 1) + (0, 1) = (90 + 3 + 0 + 0, 90 + 3 + 1 + 1):

(90 + 3 + 0 + 0, 90 + 3 + 1 + 1)

90 + 3 + 0 + 0 = 90 + 3:

(90 + 3, 90 + 3 + 1 + 1)

90 + 3 = 93:

(93, 90 + 3 + 1 + 1)
