1/5 of 80 plus 1/2 of 60 is 46. 1/5 of 80 is 16 1/2 of 60 is 30
1/5 x 400 = 80
To find the fifth number, you can use the formula for finding the average of a set of numbers. The sum of the 5 numbers is 82 * 5 = 410. The sum of the 4 known numbers is 80 * 4 = 320. Therefore, the fifth number can be found by subtracting the sum of the 4 known numbers from the sum of all 5 numbers: 410 - 320 = 90. So, the fifth number is 90.
Divide that number by 5 or Multiply it by 0.2
1/80
2/5 of 80 = 32

1/5 of 80 is 16.
1/5 of 80 plus 1/2 of 60 is 46. 1/5 of 80 is 16 1/2 of 60 is 30
1/5 of 400 is 80.
1/5 x 400 = 80
(1/5)x400 = 80
A fifth of 5 = 5/5 = 1
82-2=80 (third number) 80-6=74 (fifth number) 74-10=64 (answer) formula=ans-(x-4) Answer = 64
One-fifth is 1/5 or 0.2
1/5 x 400 = 80 0.75 x 80 = 60 80 - 60 = 20
