What decimal of 10 hours is a minute?

To express a smaller time unit as a decimal fraction of a larger span, first convert the larger span entirely into the smaller unit so both quantities share one unit, then divide the amount being measured by that total. The quotient is the amount's share of the whole, expressed as a decimal.

1. Convert the ten-hour span into minutes: 10 × 60 = 600 minutes.

2. Divide the amount being measured (one minute) by the total: 1 ÷ 600 = 0.0016666… (the digit 6 repeats).

3. Rounded to five decimal places, this is 0.00167.

Multiplying back confirms it: 0.00167 × 600 ≈ 1 (allowing for the rounding), and as a fraction 1/600 does not simplify further, so the decimal value is exact to the precision shown.

Answer: 0.00167 (= 1/600)
