Question

Use Ulrika's method to write the decimal numbers in each set in order of size, starting with the smallest. a 2.7, 2.15, 2.009 b 3.45, 3.342, 3.2 c 17.05, 17.1, 17.125, 17.42

Answer 1

Ulrika's method involves arranging decimal numbers in ascending order. You examine the numbers after the decimal point, with the smallest figures being the smallest number. This methodology is used to arrange sets of decimal numbers.

Step-by-step explanation:

From the question, Ulrika's method seems to involve arranging decimal numbers in ascending order. Which means we are placing them from the smallest to the largest.

For example, let's consider set a: 2.7, 2.15, 2.009.
To arrange this, we'd look at the numbers after the decimal point. The number with the smallest figures after the decimal point is the smallest number. So, for set a, the order would be 2.009, 2.15, 2.7.

Using the same process for sets b and c we get:
Set b: 3.2, 3.342, 3.45;
Set c: 17.05, 17.1, 17.125, 17.42.

So, this is how to order decimal numbers from smallest to largest using Ulrika's method.
