Answer:3/4
Step-by-step explanation:
1x3=3
Notice that the denominators are 3 and 7, which are factors of 21.
So express all the fractions with denominator 21:
On Monday
![\frac{1}{7} = \frac{1}{7} * \frac{3}{3} = \frac{3}{21}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B7%7D%20%3D%20%5Cfrac%7B1%7D%7B7%7D%20%2A%20%5Cfrac%7B3%7D%7B3%7D%20%3D%20%5Cfrac%7B3%7D%7B21%7D%20)
are sold
On Tuesday
![\frac{1}{3} = \frac{1}{3} * \frac{7}{7} = \frac{7}{21}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B3%7D%20%3D%20%5Cfrac%7B1%7D%7B3%7D%20%2A%20%5Cfrac%7B7%7D%7B7%7D%20%3D%20%5Cfrac%7B7%7D%7B21%7D%20)
are sold
On Wednesday
![\frac{2}{7} = \frac{2}{7} * \frac{3}{3} = \frac{6}{21}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%7D%7B7%7D%20%3D%20%5Cfrac%7B2%7D%7B7%7D%20%2A%20%5Cfrac%7B3%7D%7B3%7D%20%3D%20%5Cfrac%7B6%7D%7B21%7D%20)
are sold
by Thursday
![\frac{3}{21}+\frac{7}{21}+\frac{6}{21} = \frac{3+7+6}{21}= \frac{16}{21}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B21%7D%2B%5Cfrac%7B7%7D%7B21%7D%2B%5Cfrac%7B6%7D%7B21%7D%20%3D%20%5Cfrac%7B3%2B7%2B6%7D%7B21%7D%3D%20%5Cfrac%7B16%7D%7B21%7D%20%20)
