The answer is 12. I would do it by setting up a proportion:
8 = x
10 15
Then cross multiply to get
10x=8*15
10x=120
x=12
Question 1. 2:60 simplest form that would be 1:30
question 2. 3:5 and that is already in simplest form
Answer:
if x is by itself it's 1
Step-by-step explanation:
If a question as x=10 x is equal to the number
Step-by-step explanation:
x=2/10 - 3/5
Divide
x + 1/5=3/5
Subtract 1/5 from both sides of the equation
x + 1/5 - 1/5= 3/5 - 1/5
x=2/5
