It is: 13+20 = 33
20
it looks like 20, firstly 1 was added twice, then 2 was added twice, then 3 was added twice then 4 was added.
11 16 added 3 20 equals would be equal to a fraction 67/80.
(100 + x) = 3 (20 + x)100 + x = 60 + 3x100 = 60 + 2x40 = 2x20 = xAdd 20 to both numbers.Sums are 120 and 40.120/40 = 3/1
(3 × 1/3) ÷ 1/20 = (3/3) ÷ 1/20 = 3/3 × 20/1 = 20 → 20 twentieths are equal to three thirds.
1.) 4*1*(2+3) = 202.) 24+ 1 + 3 = 20 3.) 2(3+1)+ 4 = 20 4.) 42+ 1 + 3 = 20
20/1 + 1/3 = 20 1/3 However, I think you mean 'add one third of rwenty , to twenty'. Hence 20+(20 x 1/3) = 20 + 6.666.... = 26.6666.... or 26 2/3
3/4 * 1/20 = (3*1)/(4*20) = 3/80
First, the three numbers must be added:20 + 22 + 23 = 65Then the sum must be divided by three, because that is how many numbers there are:65 / 3 = 21 1/3The average of 20, 22, and 23 is 21 1/3.
60/3 = 20/1 = 20
-1
To find the average or mean - Add all the numbers together and divide by the amount of numbers you added: So 16 + 29 + 15 = 60 (1) (2) (3) <- So 3 numbers added together 60 / 3 = 20. So the average of 16, 29, and 15 is 20.
