Question

A30 m long peice & stringomis
lived lived divided intutwo parts in
the ratio 8:7. Find the lenight
of the two parts:​

Answer 1

Answer:

let 8 ratio 7 be 8x and 7x

Now According to question,

8x+7x= 30

15x = 30

x = 30/15

x= 2

Now value of x is 2

8x= 8 multiply2= 16meter

7x =7 multiply 2= 14 meter

Given:-

30M long wire

Ratio in which divide= 8:7

To find:-

Length of both parts

Solution:-

Procedure :- To solve such questions add the ratio given and divide by the ratio number of part which you want than multiply with part which is divide in ratio

Length of bigger part:-

$\large \: \frac{8}{8 + 7} \times 30 = 16m$

Length of smaller part

$\large \: \frac{7}{7 + 8} \times 30 = 14m$

16meter and 14 meter.
