What is the answer to the equation: 6/4=15/x ?
Nat2105 [25]
To be able to find the value of X, we have to cross multiply the two fractions then solve the equation.
As so,

6/4 = 15/x

Cross Multiply:

6 x X = 6x
4 x 15 = 60

We cross multiplied, now we can set up the equation:

6x = 60

Simplify: (Get X by itself)

Divide 6 on each side

6 / 6x = 60 / 6
x = 60 / 6
x = 10

Now we have the total of X! To check our answer, we can substitute X for 10 in the original equation.
As so:

6/4 = 15/10

6/4 = 1.5
15/10 = 1.5

Correct! Our answer is X = 10!

Hope I could help you out! If my math is incorrect, or I provided an answer you were not looking for, please let me know and I will be sure to assist you further! However, if my math was well, and correctly, explained, please consider marking my answer as <em>Brainliest!</em> :)

Have a good one!

What fraction is equivalent to 36/60 and the sum of the numerator and denominator is 24
almond37 [142]

Answer:

The fraction is \frac{9}{15}

Step-by-step explanation:

\frac{36}{60} = \frac{x}{y}

Where x and y are the numerator and denominator of our new fraction respectively.

Also given is that x + y = 24

So  \frac{x}{y} = 36 ÷ 60 = 0.6

x = 0.6y

Substituting x in x + y = 24 gives;

0.6y + y = 24 , 1.6y = 24

y = 24 ÷ 1.6 = 15

x = 24 - 15 = 9

So our fraction is \frac{9}{15}
