Frist you have to set up an equation. You know that 90 % is out of a 100 so that's one fraction. The rule for word equations like these is: is over of so therefore 45 is on top.
45 90
---- ---- Now all you do is cross multiply so 45 x100= 4500
n 100 then 4500/90 to get n
Answer:
The variable in an equation is fully equal to the solution. In an inequality, the variable is a number, but it can also be less than or greater than a number. Some solutions in an inequality even have the variable less than or equal to or greater than or equal to.
