Arecipe calls for 3/4 of flour how many cups will you need to make 3 batches answers. 1.2 3/4 2. 2 1/3 3.2 1/4 4. 2 1/2

The answer is 3. (2 1/4)
The fraction 3/4 multiplied by 3 = 9/4.
9/4 is also equivalent to 2 1/4.

So the first thing we do is to multiply the top equation by 3. the reason i want to do this is i notice there will be a 6y on both equations and can possibly add/subtract them. so we get 6y = -3x + 27. adding that and the second equation we get 6x = 27-15 which is 12. divide by 6 and we get 2. ∴ x = 2. substituting 2 into the first equation we get 2y = -2 + 9 which is 7. divide by 2 and we get 7/2. ∴ y = 7/2, x = 2.
