Step-by-step explanation:

20 + 30 + 25 + 15 + 25 = 115

115 / 5 = 23

20 - 23 = |-3|

30 - 23 = 7

25 - 23 = 2

15 - 23 = |-8|

25 - 23 = 2

3 + 7 + 2 + 8 + 2 = 22

22/5 = 4.4

$\dfrac{121}{10}\ \text{Pounds}$

Step-by-step explanation:

Given

The weight of John's backpack is

$5\ \dfrac{1}{2}=\dfrac{5\times 2+1}{2}=\dfrac{11}{2}\ \text{Pounds}$

Weight of Tyrone's backpack is

$6\ \dfrac{3}{5}=\dfrac{6\times 5+3}{5}=\dfrac{33}{5}\ \text{Pounds}$

Combined Weight of two

$\Rightarrow \dfrac{11}{2}+\dfrac{33}{5}=\dfrac{11\times5+33\times 2}{10}\\\Rightarrow \dfrac{121}{10}\ or\ 12\ \dfrac{1}{10}\ \text{Pounds}$
