1 รท (7/2)
= 1 x (2/7)
= 2/7

1 / (7/2) = 1 * (2/7) = 2/7

Dividing by a fraction is that same as multiplying by the inverse of that fraction.
(1)/(7/2) = (1)(2/7) = 2/7

Inverse means the recpitile right? so like if it was 15, it'd be 15/1 x (3/4ths) which 3/4ths is actually 4/3s? so 15/1x4/3

Math  Ms. Sue, Monday, October 4, 2010 at 5:07pm
Inverse means the reciprocal.
You only use the reciprocal when you divide.
15 / (3/4) = 15/1 * (4/3)
