Let's find a common factor for the two denominators (10 and 8) to make the two fractions combinable.
We need to find a number that can be divisible by 10 and 8 (denominators). Right off the bat, we can just multiply the two numbers and get 8 x 10 = 80.
Then let's make the numerators correspond to the denominators.
8/10 = x/80 Set up a proportion.
10x = 640 Cross-multiplication.
x = 64 Divide and simplify.
3/8 = x/80 Set up a proportion.
8x = 240 Cross-multiplication.
x = 30 Divide and simplify.
Now we have 64/80 (originally 8/10) and 30/80 (originally 3/8). Now which one is the larger number?
64/80 > 30/80
8/10 > 3/8
Answer:
Step-by-step explanation:
Subtract 57 from both sides:
Divide both sides by 4:
Answer:
A and B has the same constant of proportionality
Step-by-step explanation:
Where k is the constant of proportionality
We are supposed to find Which relationships have the same constant of proportionality between y and x as in the equation
On comparing with 1
A)6y = 3x
So, this equation has the same constant of proportionality
B)
To find the equation :
Formula :
So,
So, this equation has the same constant of proportionality
C)
To find the equation :
Formula :
So,
So, this equation do not has the same constant of proportionality
D)
To find the equation :
Formula :
So,
So, this equation do not has the same constant of proportionality
Hence A and B has the same constant of proportionality
