Answer:
40
Step-by-step explanation:
the tens value is the 2 value from the left of a decimal point.
Examples: 32 67.4 2345 904
In your case, the tens value is 4
We need to look at the ones value to see if we need to round up or down
Because the ones value, 2, is less than 5, we keep the tens value, so it's 40
