Chapter 7: Q29. (page 247)

Show that the proportions a+bb=c+dd and ab=cd are equivalent.

Short Answer

Expert verified

The given proportion is equivalent.

Step by step solution

01

Step 1. Given information.

The given proportion is,

ab=cd鈥�鈥�.

02

Step 2. Formula used.

Two proportional are said to be equivalent, if one can be obtained from the other.

03

Step 3. Proof.

It is given, ab=cd鈥�

Two proportional are said to be equivalent if one can be obtained from the other.

Again, ab=cd鈥�

Adding 1 on both sides, doesn鈥檛 change the proportion.

ab+1=cd鈥�+1a+bb=c+dd

Therefore, the given proportion is equivalent.
