9.4.5 Dividing a Denominate Number by a Whole Number
Dividing a Denominate Number by a Whole Number
To divide a denominate number by a whole number, divide the number part of each unit by the whole
number beginning with the largest unit. Ax the unit to this quotient. Carry any remainder to the next
unit.
9.4.5.1 Sample Set D
Perform the following divisions. Simplify if necessary.
Example 9.18
(12 min 40 sec) ÷ 4
Thus (12 min 40 sec) ÷ 4 = 3 min 10 sec
Example 9.19
(5 yd 2 ft 9 in.) ÷ 3
Convert to feet: 2 yd 2 ft = 8 ft .
Convert to inches: 2 ft 9 in . = 33 in .
Thus (5 yd 2 ft 9 in.) ÷ 3 = 1 yd 2 ft 11 in.
