Name a fraction that is equivalent to three twelfths and also has a denominator that is less than 12. Explain how you found your answer.

Answers

5: six twelfths is one half

6: eight tenths is four fifths

7: four eighths is one half

8: ten tenths is two halves

9: two sixths is one third

10: one quarter, because you divide the top and bottom number by 3

method:

take the first one - four eighths, which is 4/8

the question gives you what to divide them by, 4, so u divide both the top number and bottom number to get 1/2, which is one half :)

Dividing by 6 - six twelfths(6/12) = 1/2(one half)

Dividing by 2-  eight tenths(8/10) = 4/5( four fifth)

Dividing by 4 - four eighths(4/8) = 1/2 (one half)

Dividing by 5- ten tenths(10/10) = 1 = two halves(2/2) =1

Dividing by 2 -two sixths(2/6) = 1/3(one third)

The fraction that is equivalent to three twelfths(3/12) and also has a denominator that is less than 12 is one quarter(1/4).What is Division?

This operation of arithmetics involves dividing or finding out how many times one number is contained in another.

This was gotten by reducing it to the lowest fraction through dividing the numerator and denominator by 3.

Answer:

3/4 is equivalent to 9/12,

Step-by-step explanation:

So we know that 3/4 is equivalent to 9/12, because 3×12=36 and 4×9=36. A simple way to look at how to check for equivalent fractions is to do what is called “cross-multiply”, which means multiple the numerator of one fraction by the denominator of the other fraction.
