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
