Question

on the subway eight out of 11 people are carrying a briefcase based on this information if there are 700 people on the subway then about how many do not have a briefcase​

Answer 1

509 people.

$700 \div 11 = 63.6363$

$8 \times 63.6363 = 509.094$

you can't have 0.094 of someone so we round the answer off the 509.
