Three fifths of a number is exactly equal to three eighties of 40. This number is ()
40×3/8÷3/5=15×5/3=25
(1) If 20% of a number is equal to 1 / 8 of 4, find the number. (2) if 1 / 2 of a number is more than 40%, find the number
1.4 * 1 / 8 = 1 / 2 1 / 2 divided by 20% = 2.5 2.1 divided by (1 / 2-40%) = 10
5 out of 6 + (5 out of 8-3 out of 16) equals
5 / 6 + (10 / 16-3 / 16) = 40 / 48 + 21 / 48 = 61 / 48 = 1 and 13 / 48
