Question

a shoreline is eroding at a rate of one third foot per three months. How many feet are eroding per year?

Answer 1

(1/3) * 4 = ________ feet

Answer 2

(1/3)*4 =1.3

Answer 3

The answer is 1 1/3 because 4/1 times 1/3 equals 1 1/3

Answer 4

No, Ana you must be confused the answer is 4/3 because the question say's 1/3 foot per 3 months. Then it ask's what is it per year, as we all know a year is 12 month's. So you do 4x3=12 so you 1/3+1/3+1/3+1/3. (1/3 four times) That is 4/3. So the denominator always stay's the same and the numerator....well you're just doing 1x4=4 so it's pretty basic.
