Question

10/13=11/28=21/11=12/11=K. find the value of k​

Answer 1

Answer:

Mark as brainliest answer.

Step-by-step explanation:

→ First we will take

→ 10/13 = 11/28

→ 10×28/13×11

→ 280/143

→ Now we will take

→ 21/11=12/11

→ 21×11/12×11

→ 231/132

→ Now compare 280/143 = 231/132

→ 280×132/143×231

→ 36960/33033

→ Now,

→ 36960/33033

Answer 2

The value of k for the given expression, $\frac{10}{13}=\frac{11}{28}=\frac{21}{11}=\frac{12}{11}=k$ is equal to 6/7.

Step-by-step Explanation

Given: An expression, $\frac{10}{13}=\frac{11}{28}=\frac{21}{11}=\frac{12}{11}=k$

To be Found: To find the value of k in the given expression.

Solution:

We have the given expression, $\frac{10}{13}=\frac{11}{28}=\frac{21}{11}=\frac{12}{11}=k$

Here, this is an aptitude-level question.

The method used to find the value of k is by dividing the sum of equated numerators to the sum of all equated denominators.

So, k is the ratio of equated numerators to the sum of all equated denominators.

That implies,  $\frac{10}{13}=\frac{11}{28}=\frac{21}{11}=\frac{12}{11}=k$ can be converted as

$k=\frac{10+11+21+12}{13+28+11+11}$

Solving, we get

$k=\frac{54}{63}$

Simplifying, we get

$k=\frac{6}{7}$

Therefore, the value of k is equal to $\frac{6}{7}$
