Question 1098321
<br>First of all, "of" in a mathematical statement usually means multiplication.  So "4/5 of a number" means you take the number and multiply it by 4/5.<br>
For your problem, let the unknown number be x.  Then 4/5 of the number is (4/5)x, and 3/4 of the number is (3/4)x.  The problem says 4/5 of the number is 5 more than 3/4 of the number, so...
{{{(4/5)x = (3/4)x + 5}}}<br>
There are many ways to go from here to solve the problem; use whatever method you are most comfortable with.<br>
Probably the easiest for most people would be to first multiply the whole equation by the least common multiple of the denominators to clear fractions.<br>
Another clear possibility for this particular example is to convert the fractions to decimals, since both 4/5 and 3/4 have "nice" decimal representations.
