Question

find the upper bound for the following lengths: a) 14.2 cm correct to 1 decimal place b) 43.18 cm correct to 2 decimal places

Answer 1

Answer:

A) 14.25

B) 43.185

Step-by-step explanation:

A) 1 decimal place = 0.1

0.1 ÷ 2 = 0.05

+ = Upper bound

14.2 + 0.05 = 14.25

B) 2 decimal place = 0.01

0.01 ÷ 2 = 0.005

43.18 + 0.005 = 43.185
