To add these distances, they must share the same unit so first you need to first convert the swim distance from meters (m) to kilometers (km) before adding it to the bike and run distances which are already in km. To convert 300 meters to kilometers, divide the distance by 1000 to get 0.3km then add the remaining distances:

total distance = swim + bike + run
total distance = 0.3km + 40.3km + 6.1km
total distance = 46.7km

Latoya scored 77% on the test meaning she earned 77% of the possible points on the test. There were 240 possible points on the test so she earned 240 x 0.77 = 184 points. Each question is worth 4 points so she got \( \frac{184}{4} \) = 46 questions right.

To simplify a radical, factor out the perfect squares:

\( \sqrt{175} \)
\( \sqrt{25 \times 7} \)
\( \sqrt{5^2 \times 7} \)
5\( \sqrt{7} \)

A rational number (or fraction) is represented as a ratio between two integers, a and b, and has the form \({a \over b}\) where a is the numerator and b is the denominator. An improper fraction (\({5 \over 3} \)) has a numerator with a greater absolute value than the denominator and can be converted into a mixed number (\(1 {2 \over 3} \)) which has a whole number part and a fractional part.

To divide terms with radicals, divide the coefficients and radicands separately:

\( \frac{18\sqrt{25}}{6\sqrt{5}} \)
\( \frac{18}{6} \) \( \sqrt{\frac{25}{5}} \)
3 \( \sqrt{5} \)
