How can these models be used to find the sum 2.3 + 1.94?Enter your answers in the boxes. The models show a total of 3 wholes, _ tenths, and _ hundredths. After regrouping 10 tenths into 1 whole, there are _ wholes, _ tenths, and tenths _ _/_ hundredths. Therefore, the sum of the numbers is. Can someone please help me fill in these blanks.

3 whole number, 12 tenths and 4 hundredth.

3 whole number, 1 2/10 tenths and 4 hundredth.

4 whole number, 2 tenths and 4 hundredths

Step-by-step explanation:

2.3+1.94=4.24

We want to model this

Then, 2.3 can be model as

2 whole number and 3 tenths

And 1.94 can be model as

1 whole number 9 tenths and 4 hundredths

So adding the whole numbers together, we have 2+1 = 3whole number,

So adding the tenths together,

9+3=12 tenths, this already more than tenths because the tenth range for 0~9.

Adding the hundredths together

0+4= 4, this is okay, the hundredth us meant to range from 0 to 9,

So the first answer is

3 whole number, 12 tenths and 4 hundredth.

So we need to remodel the tenths because it is out of range.

12/10 = 1 remainder 2 over 10

After regrouping then, we have,

3 whole number, 1 2/10 tenths and 4 hundredth.

So the one will be added to the whole number, so the whole number will be 4 now and the tenths will be 2, which is okay because it is not in the range of 0 to 9.

Now the final answer is

4 whole number, 2 tenths and 4 hundredths
