Ruby says that 4/5 divided by 2/15 = 14/15. What error did Ruby make? A. Ruby added instead of divided. B. Ruby divided 2/15 by 4/5 instead of 4/5 by 2/15. C. Ruby divided by 2 instead of dividing by 2/15. D. Ruby multiplied by 2/15 instead of 15/2 multiplying by .

Answer:

A. Ruby added instead of divided

Step-by-step explanation:

You must find a common denominator (15), and then multiply by the reciprocal and simplify your final answer

12/15 times 15/2 equals 180/30 which, when simplified equals 6

Ruby added 4/5 and 2/15 instead of dividing. Option A is correct.

Using mathematical operations it is to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

here,
Ruby says that 4/5 divided by 2/15 = 14/15, which is incorrect.
4 / 5 divided by 2/15 is 6,
When we add both numbers,
= 2 / 15 + 4 / 5
= [2 + 12] / 15
= 14 / 15

Thus, Ruby added 4/5 and 2/15 instead of dividing. Option A is correct.
