1. X + 2 / 3-1 / 2 = 17 / 18 2. 7 / 8-25 = x + 1 / 4 x

1. X + 2 / 3-1 / 2 = 17 / 18 2. 7 / 8-25 = x + 1 / 4 x


X + 2 / 3-1 / 2 = 17 / 18
x= 1/2 -2/3 +17/18
= (9-12+17) /18
= 14/18
= 7/9
2. 7 / 8-25 = x + 1 / 4 x
7/8 -25 = 5x/4
7/2 - 100 = 5x
x = 7/10 -20 = 0.7-20 = - 19.3



What is the ratio of 0.625 to 3 / 4 and 0.3 to 0.18
