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

i dont know if you cant find a way its best to actually add all of them start from 105 tho

step-by-step explanation:

2 & 7

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.
