5/24

Simple calculation of 14 / 15 * 7

one billion eighty-four million seven hundred and eighty-four thousand three hundred and sixty
(14/15)×7
=(1-1/15)×7
=7-(1/15)×7
=7-7/15
=6 and 8 / 15

Simple calculation: 7 / 15 + 7 / 12 + 8-7 / 12

7 of 15 + 7 of 12 + 8 of 15 - 7 of 12
=(7 / 15 + 8 / 15) + (7 / 12-7 / 12)
=15 / 15 + 0
=1

7 out of 12 - (1-12 of 6 + 7 of 42) [simple operation]

7 / 12 - (1 / 6-5 / 42 + 7 / 12)
=7 / 12 - (1 / 6-5 / 12 + 1 / 6)
=7-6 of 12 + 5-6 of 12
=(7 / 12 + 5 / 12) - (1 / 6 + 1 / 6)
=1-1 / 3
=Two thirds
