You are given two decimal numbers,1.1 and 0.65. You are asked to choose a third decimal number such that it is bigger than one of the above decimals and less than the other. Which of the following would be a suitable choice?

A suitable choice would be 0.75.

To find a suitable choice, we need to compare the two given decimal numbers, 1.1 and 0.65.

Comparing the two numbers:

1.1 > 0.65

This means that we need to find a decimal number that is bigger than 0.65 and less than 1.1.

One suitable choice could be the average of the two given numbers, which is the midpoint between them.

Average = (1.1 + 0.65) / 2 = 1.75 / 2 = 0.875

So, a suitable choice would be the decimal number 0.875, as it is bigger than 0.65 and less than 1.1.

To find a third decimal number that is bigger than 1.1 and less than 0.65, we need to compare the two numbers and identify the smaller and larger one.

First, let's compare the two given decimal numbers:
1.1 > 0.65

Based on this comparison, we know that 1.1 is larger than 0.65. So, we need to find a decimal number that is larger than 0.65 but less than 1.1.

To choose a suitable decimal number, we can look for a number between the two given decimals on the number line.

0.65 and 1.1 are both decimal numbers, so we can sort them in ascending order to better visualize:

0.65 < 1.1

Now, we need to find a number on the number line greater than 0.65 but less than 1.1. One possible choice would be to choose a number between these two decimals, such as 0.75.

Thus, a suitable choice as a third decimal number would be 0.75.
