What denomination for 21/3 = 49/? Would make these ratios proportional
To make the ratios proportional, we need to find the missing value.
In the given ratio 21/3 = 49/?, we can cross multiply and solve for the missing value:
21 * ? = 3 * 49
? = (3 * 49) / 21
? = 147 / 21
? = 7
Therefore, the missing value to make the ratios proportional is 7.
To make the ratios proportional, we need to find a denomination for the second ratio, so that it is equivalent to the first ratio.
Given 21/3 = 49/?, we can solve for the unknown denominator as follows:
Cross-multiplication gives us:
21 * ? = 3 * 49
Now, we can write the equation as:
21 * x = 3 * 49
Divide both sides of the equation by 21:
x = (3 * 49) / 21
Simplifying the expression:
x = 147 / 21
Dividing 147 by 21:
x = 7
Therefore, the ratio becomes 21/3 = 49/7, and these ratios are proportional.
To determine the missing denominator that would make the ratios proportional, we need to find the relationship between the numerators and denominators.
In the given ratio 21/3 = 49/?, we can see that the numerator on the left side is 21, and the numerator on the right side is 49. To make the ratio proportional, we need to find the missing denominator that creates an equivalent ratio.
We can solve this by setting up a proportion:
21/3 = 49/x
To solve for x, we can cross-multiply:
21x = 3 * 49
Now, multiply 3 and 49:
21x = 147
To isolate x, divide both sides of the equation by 21:
x = 147/21
Simplifying the fraction, we get:
x = 7
Therefore, the missing denominator that would make the ratios 21/3 and 49/7 proportional is 7.
