As the number of pieces in a whole gets larger, the size of the pieces gets smaller. This is represented by the denominator in a fraction. As the denominator increases, the number of pieces the whole is divided into also increases so the size of the pieces is smaller.
1/2 > 1/3 > 1/4 > 1/5 etc...
Fractions get smaller as the denominator gets bigger.

Answer:
1. 11
2. -82
3. ![\frac{8}{15}](https://tex.z-dn.net/?f=%20%5Cfrac%7B8%7D%7B15%7D%20)
4. 36
5. 1
Step-by-step explanation:
1. 3x + 5, when x = 2
Plug in the value of x
3(2) + 5 = 6 + 5
= 11
2. 5xy + x - 4, when x = -3 and y = 5
Plug in the values
5(-3)(5) + (-3) - 4
-75 - 3 - 4 = -82
3.
, when a = 5, b = 3, and c = 10
Plug in the values
![\frac{6(5)(3) - 10}{5*3*10}](https://tex.z-dn.net/?f=%20%5Cfrac%7B6%285%29%283%29%20-%2010%7D%7B5%2A3%2A10%7D%20)
![\frac{90 - 10}{150}](https://tex.z-dn.net/?f=%20%5Cfrac%7B90%20-%2010%7D%7B150%7D%20)
![\frac{80}{150}](https://tex.z-dn.net/?f=%20%5Cfrac%7B80%7D%7B150%7D%20)
![\frac{8}{15}](https://tex.z-dn.net/?f=%20%5Cfrac%7B8%7D%7B15%7D%20)
4. 3(xy + 6), when x = -6 and y = - 1
3(-6*-1 + 6)
3(6 + 6)
3(12)
36
5.
, when x = -3 and y = -8
![\frac{2(-3) + 5}{3(-3) - (-8)}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%28-3%29%20%2B%205%7D%7B3%28-3%29%20-%20%28-8%29%7D%20)
![\frac{-6 + 5}{-9 + 8}](https://tex.z-dn.net/?f=%20%5Cfrac%7B-6%20%2B%205%7D%7B-9%20%2B%208%7D%20)
![\frac{-1}{-1} = 1](https://tex.z-dn.net/?f=%20%5Cfrac%7B-1%7D%7B-1%7D%20%3D%201%20)
