Question

A ratio equivalent to 3:7 is ​

Answer 1

Answer:

6:14 and 9:21 are equivalent ratios of 3:7.

Step-by-step explanation:

Equivalent ratios are the ratios which can be the identical whilst we evaluate them.

• Two or greater ratios may be in comparison with every different to test whether or not they may be equal or not.
• Ratio compares portions named as antecedent and consequent, with the aid of using the way of division

To get ,

the equivalent fractions of 3:7,

let's multiply both the ratios by the same natural number (1,2,3.....) as :

• Let's multiply by 2 .

$3 × 2 : 7 × 2 = 6 :14$

hence like this ,

• Let's multiply by 3 .

$3 × 3 : 7 × 3 = 9 : 21$

Therefore,

6:14 and 9:21 are equivalent ratios of 3:7.

Answer 2

Answer:

A equivalent ratio of 3:7 are 6:14, 9:21, and 12:28........ etc.

Step-by-step explanation:

Given that

• The ratio of 3 and 7, that is 3:7.

To find

• A equivalent ratio of 3:7

Explanation

According the Question

We have,

• The ratio of 3 and 7, that is 3:7.

For finding equivalent ratio of any given ratio

• assume a variable k, and
• k is the set of natural number (1,2,3,4.........)
• Multiply both numbers with k
• Now we have a equivalent ratios of given ratio.

So continue with that processes

• Assuming variable k a set of  natural number (1,2,3,4.........)

• Now, Multiply both numbers with k,

             = 3×k : 7×k    --------------------------(1)

Let's consider it as equation (1)

Putting the values of k in equation (1)

When k = 2,

Then,

             = 3×2 : 7×2

             = 6: 14

When k = 3,

              = 3×3 : 7×3

            = 9: 21

And when k = 4,

              = 3×4 : 7×4

             = 12: 28

So

A equivalent ratio of 3:7 are 6:14, 9:21, and 12:28........ etc.
