Y KM TUITION r upper and lower Page 1 of 8 upper and lower Bounds In this exercise we a re going to look at upper and lower bounds. We shall explore numbers rounded to the nearest 10, 100 or 1 and work out the lowest and highest values of the original rounded values. World s strongest man claims he can lift 70kg with his little finger rounded to the nearest 10kg. What is the smallest amount he can lift? Here we have to think of all the numbers that can be rounded up to give 70. A number line would be useful here to observe these numbers. The numbers shown in red can be rounded up to give 70. This means the smallest amount the world s strongest man claims to lift is 65kg which is the smallest number shown on the number line.
