Answer: 2.3
Step-by-step explanation:
We are given the mixed number [tex]2\dfrac{3}{10}[/tex] and a model. With this information, we can write a decimal equivalent for this amount.
The model shows two wholes. We will write this in the one's place as 2.
Next, the model shows a part of a whole, the decimal. This is the [tex]\dfrac{3}{10}[/tex] portion. The place value after the decimal (x.xx) is the tenth's place. Since this fraction is in tenths, we can write the decimal as 0.3, since it's three-tenths.
In full, this gives us 2.3. You can also do 2 + 3/10 = 2.3.
