Answer:
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
