km. Express your answer as a mixed number or improper fraction in lowest terms.
? km2

Answer 1

multiply both the numbers to get the area

Answer 2

Area = length x width
= (2 4/5) * (3 1/8)

Answer 3

2 4/5 is same as 2+4/5

Answer 4

3 1/8 is same as 3+1/8

Answer 5

\[\large \left(2+\frac{4}{5}\right) * \left(3+\frac{1}{8}\right)\]

Answer 6

5 4/40

Answer 7

get common denominator and add the fractions first

Answer 8

\[\large \left(2+\frac{4}{5}\right) * \left(3+\frac{1}{8}\right)\]

\[\large \left(\frac{2*5}{5}+\frac{4}{5}\right) * \left(\frac{3*8}{8}+\frac{1}{8}\right)\]

\[\large \left(\frac{10}{5}+\frac{4}{5}\right) * \left(\frac{24}{8}+\frac{1}{8}\right)\]

\[\large \left(\frac{14}{5}\right) * \left(\frac{25}{8}\right)\]
