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

#15. square

step-by-step explanation:

because quadrilatural (idk how to spell it) means somthing that is not 3d or like, equal sides (or somthing like that   you know what i meanz)

hope this halps!

bai!

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides
