48/15 - 32/25 = 68/15 - 77/25 = 340/75 - 231/75 = 109/75 = 134/75
225/300 = 3/4
-3 - 4 = -7 (minus seven)
-1
-4 + -3 = -7
Suppose the principle is Y and the interest rate r. Then Y + 3rY = 815 Y + 4rY = 854 rY = 39 So Y + 3*39 = 815 Y = 815 - 3*39 = 815 - 117 = 698
(-3)-(4)=(-3)+4=1 Minus times minus equals plus. The reason for this we need not discuss.
-1
225 divided by 3/4.........well, since 3/4 is equal to 0.75, then you would divide 225 by 0.75.......in which case the answer would be 300
-3 - (-1)= -3 + 1= -2-2
-4 - 112 = -4 - 121 = -125 (-4 - 11)2 = -152 = 225
4/7 minus 3/4 is -5/28
It is 3 minus 4 = -1
