Question

3. A student finished 8 of her homework
problems in the class. If the ratio of the
problems she finished to the problems she
still has left is 4:1, how many homework
problems did she have in total?

please solve it ​

Answer 1

Answer:

Using the ratio we are given

4:1 we can use it to find the amount we need

4/1 = 8/x

do cross multiplication

(4)(x)= (8)(1)

4x = 8

divide both sides by 4 to isolate the x (it stands for the amount of assignments she still has left)

x = 2

So if she finished 8 assignments and still has 2 to do

8 + 2  

She has a total of 10 homework problems

Hope this helps :)
