Okay i don't know how to do this?
13-b 2- 0.5b
------ ---------
6 4
How do i solve ths proportion?
From the way you have it written, I'm not sure what you mean. Do you mean:
([13-b]/64)(2-.5b)?
Please repost with information give more clearly.
I hope this helps a little. Thanks for asking.
the answer is 40
To solve this proportion, you need to find the value of 'b' that makes the two fractions equal to each other. To do this, you can cross-multiply and then solve for 'b'.
Step 1: Multiply the numerator of the first fraction by the denominator of the second fraction.
(13 - b) * 4
Step 2: Multiply the denominator of the first fraction by the numerator of the second fraction.
6 * (2 - 0.5b)
Step 3: Set the two resulting expressions equal to each other.
(13 - b) * 4 = 6 * (2 - 0.5b)
Step 4: Simplify the equation by expanding the expressions on both sides.
52 - 4b = 12 - 3b
Step 5: Move all the terms with 'b' to one side of the equation.
-4b + 3b = 12 - 52
Step 6: Combine like terms.
-b = -40
Step 7: Divide both sides of the equation by -1 to isolate 'b'.
b = 40
Therefore, the value of 'b' that solves the proportion is 40.
