solve the proportion 5.2 / 8 equals y / 6
A: y = 4.22
B: y = 6.93
C: y = 2.86**
D: y = 3.90
Can you please check me? If I am wrong, please tell me what I need to do to make it right.
Oh, nevermind! I got the answer it's D
3.90 is the answer!!
Solve the proportion.
6
8
=
24
y
y=?
So, lemme help
The proportions are 5.2/8=y/6
So,
So if you cross multiply 5.2 and 6
5.2 x 6 = 31.2 and now you do 8 times x which is 8x so
31.2 8x so to get the x by it self you have to do something with the 8
8x you have divide to take the 8 away and what ever you do to 1 side you have to do to the other so
31.2 ÷8 =$3.90 I put the zero there because we're dealing with money
omg thx
Well, let's see if we can solve this proportion together! To solve a proportion, we need to set up an equation. In this case, we have 5.2 divided by 8 equals y divided by 6. We can write this as:
5.2/8 = y/6
To solve for y, we can cross multiply. That means multiplying the numerator of the first fraction with the denominator of the second fraction, and vice versa. So we get:
(5.2)(6) = (8)(y)
31.2 = 8y
Now, we can solve for y by dividing both sides of the equation by 8. That gives us:
31.2/8 = y
y = 3.9
So, the correct answer is D: y = 3.90.
Sorry to burst your bubble, but C: y = 2.86 is not the correct answer. But don't worry, proportions can be tricky sometimes. Keep practicing, and I'm sure you'll master them soon!
To solve the proportion 5.2 / 8 = y / 6, you need to cross-multiply and then solve for y.
First, cross-multiply by multiplying the numerator of the first fraction (5.2) by the denominator of the second fraction (6), and multiply the denominator of the first fraction (8) by the numerator of the second fraction (y):
(5.2) * (6) = (8) * (y)
Next, simplify the equation:
31.2 = 8y
To solve for y, divide both sides of the equation by 8:
31.2 / 8 = y
This gives us:
y = 3.9
So, the correct answer is:
D: y = 3.9
Therefore, your initial answer of C: y = 2.86 is incorrect. The correct value for y is 3.9.
