What percentage of the students still receive an allowance
Mariana [72]

Answer:

I most likely think it is approximately 19%

Step-by-step explanation:

Assuming you mean still receive an allowance even though they dont do chores:

Ok In all the total number of students is 21. Out of those 21, 4 still receive an allowance even though they dont do chores. This is 4/21. Now all we have to do is convert 4/21 into a percentage. To do this we have to divide 100 by 21, then times 4 by that number:

100 / 21 = >> approximately 4.76

Now 4 times 4.76 :

4 * 4.76 = >>> approximately 19.04 % . We round it to 19%.


So the answer is 19%.
