<span>We can say that 20 students represent 100 % and that 4 students represent x % of all students. Then we can use the proportion: 20 : 4 = 100 : x, or 20 / 4 = 100 / x. Then we will cross multiply: 20 x = 4 * 100, 20 x = 400, x = 400 : 20 , x = 20 %. Also we can say that 4 = 1/5 * 20 and 1/5 * 100 = 20 % Answer: 4 students is 20 % of 20 students. Hope this helps. Let me know if you need additional help!</span>
<span>1. </span><span>Well if the quotient is 45 ¼, the
divisor will depends on the dividend.
Since the dividend is not given, there it would be hard for us to tell what is
the divisor.
Because we only have the quotient, there are a lot of answers then if the
dividend is not given.
it can be that the divisor is 2 and the dividend is 90 ½ to be able to get 45 ¼
as an answer.
it’s hard to tell without identifying the dividend.</span>
