Answer:
Mark will eat 3 Tacos
Explanation:
12 is a number that is easily divisible by 4. If you take 12 and divide it by 4, you get 3.
If you were to multiply that 3 by 2, you would have two 1/4 parts of 12, which would be 1/2 of the tacos
But since Mark only ate 1/4 of the tacos, 12/4 = 3 and 3 is one part of the 4 parts that equal 12
So Mark will have ate 3 tacos!
Hope this helps : )
