The feeders in battling machine are represented in proportions and fractions.
- The equation that represents the problem is:

- The feeder can hold <em>30 baseballs</em>, when full
The given parameters are:
<em />
<em> ------ 1/6 full</em>
<em />
<em> --- baseballs added</em>
<em />
<em> ---- 2/3 full</em>
<em />
So, the equation that represents the problem is:

So, we have:

The number of baseballs it can hold is calculated as follows:

Multiply through by 6

Collect like terms


Divide through by 3

Hence, the feeder can hold 30 baseballs, when full

The answer should be 21 hope it helps
Find ing the common denominator would make it 10.
for 1/2 to get to 10 you have to multiply by 5
1/2x5= 5/10
then you have to convert 2/5 to get the denominator to be 10
so you multiply 2/5 by 2
2/5x2= 4/10
5/10 is greater than 4/10
