Question

David a line segment of length 15cm in 5:2 ratio​

Answer 1

Answer:

First part = 10.7cm

Second part = 4.28cm.

Step-by-step explanation:

Let the parts of the segment be 5x and 2x respectively.

According to the question,

$5x + 2x = 15 \\ 7x = 15 \\ x = \frac{15}{7} \\ x = 2.14$

Here, First part = 5x = 5 × 2.14 = 10.7cm

Second part = 2x = 2 × 2.14 = 4.28cm.

Answer 2

As per the data given in the above question.

In the above question, it is given that,

The given data is Length of a line 15cm,

The ratio is 5:2

We have to find the value in given ratio.

Thus, solving the equation we get,

Let the value be 5x and 2x,

The total length is equal to sum of ration,

$5x+2x=15\\7x=15\\x=\frac{15}{7}$

So the ratio will be,

$5x=5\times \frac{15}{7} \\=10.7cm$

$2x=2\times \frac{15}{7} \\=4.3cm$

Hence the value of ration is 10.7cm and 4.3cm.
