Question

Multiply the first number by its reciprocal

try to explain in the most easiest way as possible plz and thank you ​

Answer 1

Answer box1 : 42
Answer box2 : 1

I always remember REciprocal = REverse the fraction. So the of 6/7 is going to be 7/6 and so on.

Now you can just think of it like regular multiplication. You can spilt it into 2 problems (top and bottom)

6 x 7 = 42
7 x 6 = 42

Any number over itself always equals 1, so that means anytime you multiply a fraction by its own reciprocal, your answer will always be 1

I hope this helps :)

For example- 2/1 × 1/2 = 1 . Every number has a reciprocal except 0 (1/0 is undefined)
