Answer:
5/105
Step-by-step explanation:
Since it's basically 5/7 divided by 15, you would set it up like this. All of my work is on the sheet, I can explain more if it is necessary.
Answer: 1/21
(5/7)/15
= (5/7)×(1/15)
= 5/(7×15)
= (5/5)/(7×15/5)
= 1/21
gwen- 15times 2
alex-15 plus 7
15 times 2 is 30
15 plus 7 is 22
30 plus 22= 52
52 plus 15= 67
-90= 5y-20
-90+20= 5y-20+20
-70=-5y
-70/-5= -5y/-5
y= 14
