Answer:
basically it’s a process called cross multiply
ur dealing with ratios and your trying to find n (variable) that is equal to this:
[tex]\frac{n}{9} = \frac{10}{15}[/tex]
Step-by-step explanation:
Step 1: write the cross products
(ex: [tex]\frac{n}{9} = \frac{10}{15}[/tex])
Step 2: multiply the numbers
(ex: [tex]9x10[/tex])
Step 3: solve the equation using INVERSE operations
(meaning the oopposite like if it were addition we’d do the opposite which subtraction just multiplying and then doing division the OPPOSITE)
If you were doing it like a ratio this is how you would do it:
Since
X : 9 = 10 : 15
Then we know
X/9 = 10/15
Multiplying both sides by 9 cancels on the left
9 × (X/9) = (10/15) × 9
X = (10/15) × 9
Then solving for X
X = 9 × (10/15)
X = 6
Therefore
6 : 9 = 10 : 15
hope this helped. please mark brainliest! :) bye!
