Well 4 just means that there are 4 of these things. so 1/2 is also the same as 50/100 or 25/50 or 500/1000 (the gist of it) so you just multiply the bottom and the top by the same number which would just give you different improper fractions
Out of every 11 students 7 were girls. Set up the following proportion.

We can use the formula to solve for A, the area. The formula is:
A=1/4 · π · d^2.
So let’s use this to solve the diameter of the button.
1/4·π·8^2≈50.26548
We can then round to a final answer of 50.27.
Hope this helps!
