(97.5m/5m) * 1cm =
To determine the position of a number in a list, you can follow these steps:
(a) To find the number that is halfway in a list of 10 numbers:
Step 1: Divide the total number of items in the list by 2.
10 ÷ 2 = 5
So, the number that is halfway in a list of 10 numbers is the number at the 5th position.
(b) To find the number that is a quarter of the way in a list of 10 numbers:
Step 1: Divide the total number of items in the list by 4.
10 ÷ 4 = 2.5
Since we cannot have a fraction as a position, we round up to the nearest whole number.
Round(2.5) = 3
So, the number that is a quarter of the way in a list of 10 numbers is the number at the 3rd position.
(c) To find the number that is three quarters of the way in a list of 10 numbers:
Step 1: Divide the total number of items in the list by 4.
10 ÷ 4 = 2.5
Since we cannot have a fraction as a position, we round down to the nearest whole number.
RoundDown(2.5) = 2
Then, we add three-quarters of the total number of items to the rounded-down value.
2 + (3/4 * 10) = 2 + 7.5 = 9.5
Since we cannot have a fraction as a position, we round up to the nearest whole number.
Round(9.5) = 10
So, the number that is three-quarters of the way in a list of 10 numbers is the number at the 10th position.
