Seven minus four and a half is two and a half.
4/7 * 1/6 = (4*1)/(7*6) = (2*1)/(7*3) = 2/21
2/7 + 1/4 (2*4)/(7*4) + 7/(4*7) 8/28 + 7/28 (8 + 7)/28 15/28
14/1 * 2/7 = 2 14/1 * 2/7 1 = 2*2 = 4
7/16 x 4/3 x 1/2 = 7/24
4=1*2*27=1*71*2*2*7=28
(-3/4)*(-1/3) + (7/8)*(-1/2) = (3/4)*(1/3) - (7/8)*(1/2) = 1/4 - 7/16 = 4/16 - 7/16 = -3/16
14/4 = 7/2 or 3 and 1/2
1/4 x 16/7 = 4/7
2/5(9-7)/(1+4)Simplify 9-7 to 2.2/(1+4)Simplify 1+4 to 5.2/5
21/3 * 1/4 = 7/3 * 1/4 = 7/12
That's the same as 7/8 x 4/1 = 28/8 or 7/2 or 3 and 1/2
7 - 4.75 = 2.25 = 2 and 1 over 4.
