How do you write 1is to 2 as 5 is to x as a proportion in fractional notation
To write "1 is to 2 as 5 is to x" as a proportion in fractional notation, we can use the formula:
a/b = c/d
In this case, the given values are "1 is to 2" and "5 is to x". Substituting these values into the formula:
1/2 = 5/x
So, the proportion in fractional notation is 1/2 = 5/x.
To write "1 is to 2 as 5 is to x" as a proportion in fractional notation, follow these steps:
Step 1: Write the first ratio as a fraction.
The first ratio is "1 is to 2." So, we can write it as 1/2.
Step 2: Write the second ratio as a fraction.
The second ratio is "5 is to x." So, we can write it as 5/x.
Step 3: Set up the proportion.
We set the two fractions equal to each other: 1/2 = 5/x.
Step 4: Solve for x.
To solve for x, we cross multiply: 1 * x = 2 * 5.
Step 5: Simplify the equation.
Simplifying the equation gives us: x = 10.
Therefore, the proportion in fractional notation is 1/2 = 5/10.
To write the proportion "1 is to 2 as 5 is to x" in fractional notation, you need to express the ratios using fractions.
The given ratio states that the relationship between 1 and 2 is equivalent to the relationship between 5 and x. Let's set up the proportion:
1/2 = 5/x
To find x, we can solve for it by cross-multiplying. Cross-multiplication involves multiplying the numerator of the first fraction with the denominator of the second fraction, and vice versa. Like this:
1 * x = 2 * 5
Simplifying the equation:
x = 10
So, the fractional notation of the proportion "1 is to 2 as 5 is to x" is:
1/2 = 5/10
