Round to the nearest tenth: 430.09

When you see 2 numbers behind the decimal and when you see the second number greater than 5 and the first number is a zero or a number below 5 the second number (9) rounds the zero (first number) and the 9 turns the zero to a 1 hope that makes sense

The answer would be 430.1, because the tenths place is the zero after the decimal and the 9 is larger than five so you would round up and that would become 1.
