Upper and Lower Bounds - Subtracting and Dividing

If u = 99 and k = 82 have been rounded to the nearest whole number, find the highest possible value of u ÷ k.

If z = 8.7 and s = 1.5 have been rounded to 1 decimal place find the lower bound of z - s

Answer explanation

8.65-1.55 = 7.1

If v = 4.1 and b = 5.7 have been rounded to 2 sig figs find the upper bound of v ÷ b

If n = 7.23 and m = 4.25 have been rounded to 2 decimal places find the upper bound of n - m.

Answer explanation

7.235 - 4.245 = 2.99
