The LCM of 8 & 20 is... 40
The smallest number that 8 or 12 or 20 will all go in to is 120 120 = 20 x 6 = 12 x 10 = 8 x 15 as there is then no number that goes into 6 and 10 and 15 equally.
20 equals 8 more than a number y 20=y+8
8 / 0.2 = 40 Therefore, the number that 8 is 20 percent of is 40.
8 / 0.4 = 20 Therefore, 8 is 40 percent of 20.
20/8 = 21/2
2.5
8 / 0.2 = 40 Therefore, 20 percent of 40 is 8.
1, 2, 4, 5, 8, 10, 20, 40
Adding a % and a whole number: Example: 50% of 20 + 8 = 50% x 20 + 8 = 0.50 x 20 + 8 = 10 + 8 = 18
8 is 40% of 20
22 + 8 - 10 = 20 Therefore, the number he is thinking of is 22.
8 is 20% of the number 40.40 - 32% (12.8) is 27.2.So your answer is 27.2! ;)
