To solve, the first step is to find the LCM (least common denominator). In this scenario, it's ten.
6 5/10 - 2 3/10
From here, do the math. It's easy this time, what's 5 - 3? Two.
Now, subtract two from six. (four)
4 and 2/10
4 and 1/5
There! :)
density = mass / volume
4 = 35 / v
v = 35/4 = 8.75 cm^3

Question 3 can be re-written as:
which equals:
Question 4 can be re-written as:
Doing the first 2 brackets gives us:
Expanding these two:
Simplifying it:
Divide the amount donated by total sales then multiply by 100.
350 / 8750 = 0.04
0.04 x 100 = 4%
