Answer

The response given most often is totally honest. 400 responded totally honest. $\frac{7}{12}$ responded totally honest or fib a little.

Work Step by Step

$\frac{1}{3}$ is larger than the other fractions, so the response given most often is totally honest. $1200 \times \frac{1}{3}$ = $\frac{1200}{3}$ = 400 400 responded totally honest. $\frac{1}{3} + \frac{1}{4}$ Multiply the denominators to find the LCM of 12. $\frac{1}{3} + \frac{1}{4}$ = $\frac{4}{12} + \frac{3}{12}$ = $\frac{7}{12}$
