In this situation you will need to do 8 divided by 25 which will give the answer 0.32.
Theres a saying: Dividing fractions dont ask why, just flip the second and multiply.
so a/b / c/d = a/b * d/c
-8/2 * -3/6
1. cross - cancel common factor 2
4/2 * -3/3
2. Multiply
-4(-3)/ 2*3
3. multiply numbers
--12/2*3
- -12/6
4. Apply fraction rule -a/b=- a/b
=-(-12/6)
5. divide
= -(-2)
6. Apply rule -(-a)=a
=2
Your answer would be 2
8. 1,728 i did 12×18÷2=108×32=345÷2= 1,728
37.5 % of 800 is 300 because of division
F(n)=3n-2
Plug in 2 for n. f(2)=3(2)-2=4
