N=-3/20
In decimal form it would be n=-0.15
So you're trying to find what number is like that right? Well multiply the denominator by the 20 (20*4) which equals 100, so 100-20 (the one fourth) is 80. So 3/4 fourths of 100 is 20.
Equation of a line: y=mx+b
m=slope(-1)
b=y-intercept(-7)
y=-1x-7 or y=-x-7
99=3/8g+2+12g+2
-4 -2 -2
95=3/8g+12g
95=12(3/8)g
(Divide both sides by 12(3/8))
