why all the words? You showed the math. Just solve the way you normally would; don''t let the fractions confuse things.
1/2.75 = 1/3.2 - 1/x
1/x = 1/3.2 - 1/2.75
1/x = (2.75-3.2)/(3.2*2.75)
x = (3.2*2.75)/(2.75-3.2) = 8.8/-0.45 = -19.556
Or, just convert to decimals at first:
0.363636 = 0.3125 - 1/x
0.05113 = -1/x
x = -19.556
Hey! I need some help with this question! I totally forget how to do these types of problems!
1 over 2.75 = 1 over 3.2 - 1 over x
( 1/2.75 = 1/3.2 - 1/x) / = fraction bar
