2 is 1 and 4 is 3.
4!/(2!*2!) = 4*3*2*1/(2*1*2*1) = 6 4!/(2!*2!) = 4*3*2*1/(2*1*2*1) = 6 4!/(2!*2!) = 4*3*2*1/(2*1*2*1) = 6 4!/(2!*2!) = 4*3*2*1/(2*1*2*1) = 6
-2 3/4 - 1/4 = -(2 3/4 + 1/4) = -[2 (3+1)/4] = -(2 4/4) = -(2 + 1) = -3 or -2 3/4 - 1/4 = - (4*2 + 3)/4 - 1/4 = -11/4 - 1/4 = (-11 - 1)/4 = -12/4 = -3

2 and 3/4 - 1 and 1/2 is 1 and 1/4. 2 - 1 = 1. 3/4 - 1/2(2/4) = 1/4 = 1 and 1/4 -5/6

one and a half 1/2 = 2/4 half of 2/4 = 1/4 2/4 + 1/4 = 3/4 ------------------------------------------- 3/4 ÷ 1/2 = 3/4 × 2/1 = (3×2)/(4×1) = 6/4 = 3/2 = 1½
