Question

16. A rod is broken into two parts such that the smaller parts of
length 6.3cm.If the ratio of the two parts is 7:3. find:
(a) the length of the longer part.
(b) the total length of the original rod.
​

Answer 1

(a) 14.7 cm and (b) = 21 cm.

Step-by-step explanation:

A rod is broken into two parts such that the smaller parts of  length 6.3 cm.

Now, if the ratio of the two parts is 7 : 3, then

(a) The length of the longer part will be $6.3 \times \frac{7}{3} = 14.7$ cm.

(b) The total length of the original rod is = (Length of larger part + Length of smaller part) = (6.3 + 14.7) = 21 cm.(Answer)
