To work out percentage, divide what they've done (21) by the total distance (50), then multiply it by 100 to get the percentage
(21/50)*100 = 42%
If you have 5 flavors and 11 toppings, but you can only have 1 of each you take 5×11 to get 55

In the pic3 you can calculate "x" from the equation:
0.4=40%
75%=3/4
0.64=16/25
30%=0.3
3/20=15%
Simplify the expression first by the "flip and multiply" method. We end up first with:
[x(x-3)]/[x⁻¹(x+4)]
Simplifying further we have:
[x²(x-3)]/(x+4)
Solving for restriction we equate the denominator to 0:
x + 4 = 0
x = -4
x≠4 (-4 is a restriction of the expression)
