Answer and Explanation
For the initial value, we can see that we have two whole squares and one partial square. The partial square is divided into 100 equal parts, of which 28 are filled.
We can represent this value by adding a fraction representing the partial square to the whole filled squares:
[tex]2 + \dfrac{28}{100}[/tex]
In decimal form, this is:
[tex]2.28[/tex]
Now, from that initial value, we can see that the following are crossed out:
- 1 whole square
- 5 rows which are 1/10 square each (3 in the middle one and 2 in the right one)
- 5 small squares which are 1/100 square each
Putting these subtracted parts together, we get:
[tex]1 + \left(5 \times \dfrac{1}{10}\right) + \left(5 \times \dfrac{1}{100}\right)[/tex]
[tex]=1.55[/tex]
Thus, our difference expression is:
[tex]\text{ }\ \ \, 2.28 \\ \underline{-\ 1.55}[/tex]
We can evaluate this as follows:
[tex]\text{ } \ \ _1 \: _{12} \\ \text{ }\: \not 2.\!\!\!\not28 \\ \underline{-\ 1.55} \\ \text{ }\ \ \, 0.73[/tex]
