4! * 2 + 3 - 1 = 24*2 + 3 - 1 = 48 + 3 - 1 = 50
One way is 2*4! + 3 - 1 = 2*24 + 3 - 1 = 48 + 3 - 1 = 50

1/2 = 2/4 3/4 - 1/2 = 3/4 - 2/4 therefore 3/4 - 1/2 = 1/4 A slightly simpler way, just my opinion. 3/4 - 3 divided by 4 = .75 1/2 - 2 divided by 1 = .50 .75 - .50 = .25 which is a quarter (1/4) I guess it would be how you want to calculate it...
2/3 and 1/2(2/3) / (1/2) = 11/3 ≈ 1.33"of" (as in BODMAS) I was taught meant times , as is 50% of 30 is 50% x 30, so:2/3 of 1/2 = 2/3 x 1/2= 1/3≈ 0.33
50% or 1/2 of 2 is 1, so 50% or 1/2 more than 2 would be (2 + 1) = 3
(1 + 2 + 3 + ... + 49 + 50)/50 = (1 + 50)/2 = 25.5
50% is the same as 1/2 .1/2 is 25% less than 2/3 .
1/3 of 50 is 16 2/3.
1+2 = 3 1+2+3 = 6 1+2+3+4 = 10 1+2+...+ N = 1/2(N+1)N if N = 50, 1+2+...+50 = 1/2 x 51 x 50 = 1275 Since 2+4+6+...+100 = 2 x (1+2+3+...+50) = 2 x 1275 = 2550
Here are the first 3 numbers less than 50: 50 - 1 = 49 50 - 2 = 48 50 - 3 = 47 The numbers before it would be the answer too.
16 2/3 = 50/3, multiplied by 1/3 = 50/9 which is 5 and 5/9.
