Question

A number, a, rounded to 1 d.p. is 49.3

Answer 1

For the given numbers, the lowest bound : 41.66. the upper bound: 42.19

How are upper and lower boundaries discovered?

To determine a rounded number's upper and lower bounds: Determine the place value of the claimed level of accuracy. By two, multiply this place value. Find the upper bound by adding this amount to the provided value, and the lower bound by deducting this amount from the given value.

The lower: a=49.35. b=7.69

so the lower bounds is:

a-b=49,35-7.69 =41.66 = a=49.49.34.

b=755 the upper = a= So the upper bounds is = a-b= 42.79.
