I think the answer's 7/8. If you convert 1/4 to 2/8 and add them together, you add 5/8 and 2/8 to get 7/8.
Divide by the coefficient of y.
y = (45/9)x
y = 5x
The constant of proportionality is 5.
In my opinion the concepts that belong in the branch of mathematics would be algebra, geometry, trigonometry, calculus, statistics, and probability. All of the following are known the be main branches of pure mathematics.

Answer:</h3>
8/13
<h3>
Step-by-step explanation:</h3>
Given in the question
Ratio of sandwiches white bread to brown bread is 10 : 3
white bread fraction = 10/13
brown bread fraction = 3/13
It is also provided that
2/3 white are vegetarian
1/2 brown are vegetarian
So
for white bread vegetables sandwich we will find 2/3 of 10
20/3/13
for brown bread vegetable sandwich we will find 1/2 of 3
3/2/13
adding both
20/3/13 + 3/2/13
8/13 (approximate)
