So we need have to understand that if we were to solve this, our answer would be 7 less than 'p' with that information we get p-7.
You would basically go back and trace all your steps, that's what I do. And if your answer seems reasonable then you have the right answer but if your work doesn't match the answer than you've messed up.
I hope I helped if I did like my answer and comment down below thx
Answer:
E, 5:2
Step-by-step explanation:
1:2
1/3 x 30 = 10 . 2/3 x 30 = 20
1:1
1/2 x 30 = 15
3:7
3/10 x 30 = 9 7/10 x 30 = 21
4:1
4/5 x 30 = 24 . 1/5 x 30 = 6
5:2
5/7 x 30 = 21.43 (this is a decimal so it does not work)
Your answer is 4
Hope this helps.
