In order to subtract the numerators of a fraction, the denominators need to be equal. In order to do that, you need to multiply \(\frac{3}{4}\) x \(\frac{2}{2}\) to get \(\frac{6}{8}\). So now we can think of the problem "what times \(\frac{3}{8}\) equals \(\frac{6}{8}\). So the answer is 2. The food will be up in 2 weeks.
