When you're rounding to the one's place, that means the digit directly to the right (the tenth's place) is used to know how to round. If that digit is 5 or above, you round up the digit in the one's place. If it is 4 or below, you keep the one's digit as it is.
For your number 37.7, that would round to 38 if you're rounding to the one's place.
