If 2/7 were absent, the 1950 present were 5/7 of the entire student body
We can divide 1950 by 5/7 to get the whole, or invert and multiply:
(1950)(7/5)=2730 ANSWER The total number of students are 2730.
--OR--
Convert to percentage: (5/7)(100%)=71.43%
Divide 1950/0.7143=2729.95 or a total of 2730 for the entire student body.
