Five books on Lisa's reading list are fiction.
If this is 20% of her entire reading list, how many books does Lisa have in all?
would it be 15
Let's check that out.
15 * 0.2 = 3
Nope. That didn't work.
Let's try this.
0.2x = 5
Solve for x.
ok it will be 1
i got 1 at first but i did not understand it
1 doesn't make any sense.
0.2x = 5
x = 5 / 0.2
x = ?

No. How can 20 percent of 2.5 be 5?
Divide 5 by 0.2

Yes.
