<u><em>Answer:</em></u>
Mrs. Hong originally had 900 ml of milk
<u><em>Explanation:</em></u>
The complete question is in the attached image
Assume that the amount of milk Mrs. Hong originally had was x ml
<u>We are given that:</u>
1- She used
of it to bake the waffles, <u>therefore</u>:
Amount used in baking waffles =
ml
2- She used 300 ml to bake a pie
3- Amount left is half the original amount, <u>therefore</u>:
Amount left =
ml
<u>We know that:</u>
Total amount = amount used in waffles + amount used in pie + amount left
<u>Substitute with the givens and solve for x:</u>
Total amount = amount used in waffles + amount used in pie + amount left
![x = \frac{1}{6}x + 300 + \frac{1}{2}x\\ \\x-\frac{1}{6}x-\frac{1}{2}x = 300\\ \\\frac{1}{3}x = 300\\ \\x = 300*3 = 900 ml](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B1%7D%7B6%7Dx%20%2B%20300%20%2B%20%5Cfrac%7B1%7D%7B2%7Dx%5C%5C%20%20%5C%5Cx-%5Cfrac%7B1%7D%7B6%7Dx-%5Cfrac%7B1%7D%7B2%7Dx%20%3D%20300%5C%5C%20%20%20%5C%5C%5Cfrac%7B1%7D%7B3%7Dx%20%3D%20300%5C%5C%20%20%5C%5Cx%20%3D%20300%2A3%20%3D%20900%20ml)
<u>This means that:</u>
She originally had 900 ml of milk

Answer: ![\frac{13}{35}](https://tex.z-dn.net/?f=%5Cfrac%7B13%7D%7B35%7D)
Step-by-step explanation:
negative 3 over 7= ![-\frac{3}{7}](https://tex.z-dn.net/?f=-%5Cfrac%7B3%7D%7B7%7D)
Plus 4 over 5= ![\frac{4}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B5%7D)
When adding fractions together, you should first change into a common denominator, then do the operation.
------------------------------------------------------------------------------------------------
= ![-\frac{15}{35}](https://tex.z-dn.net/?f=-%5Cfrac%7B15%7D%7B35%7D)
= ![\frac{28}{35}](https://tex.z-dn.net/?f=%5Cfrac%7B28%7D%7B35%7D)
+![\frac{4}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B5%7D)
=
+![\frac{28}{35}](https://tex.z-dn.net/?f=%5Cfrac%7B28%7D%7B35%7D)
=![\frac{13}{35}](https://tex.z-dn.net/?f=%5Cfrac%7B13%7D%7B35%7D)
Hope this helps!!
