To convert tenths to minutes, what is the correct method?

To convert tenths to minutes, multiplying by 60 is the correct method because each minute is divided into tenths when measuring time in a decimal format.

When you have a measurement in tenths (for example, 0.5 represents half of a unit), you can think of this as 0.5 of an hour. Since there are 60 minutes in an hour, you convert the decimal by multiplying by 60 to obtain the equivalent number of minutes. So, if you take 0.5 (which is half of an hour) and multiply it by 60, you get 30 minutes.

This method works consistently across the range of values where tenths are expressed in hours, converting them accurately into minutes. In contrast, adding or subtracting 60 would not provide a conversion but rather distort the original time measurement. Dividing by 10, on the other hand, would reduce the value rather than convert it to a more useful time unit.
