Answer :
Answer:
423.1
Step-by-step explanation:
423.812, 436.087, 423.01, 423.1
423 < 436, so 436.087 must be the greatest number.
Let's move it to the right.
423.812, 423.01, 423.1, 436.087
The three number to the left start with 423.
Now we look at the next place to the right, the tenths place.
423.812, 423.01, 423.1
The digits in the tenths places are 8, 0, 1.
In ascending order they are 0, 1, 8.
Now we place the three 423 numbers in ascending order using the digits in the tenths places.
423.01, 423.1, 423,812
Finally, we place the 436 number at the right.
423.01, 423.1, 423,812, 436.087
The second number in ascending order is 423.1
