The product of the two factors is 82.4. If one of the factors increases by 6 times and the other decreases by 2 times, what is the product? Well written

Answer: 247.2
1. One factor expands six times, so does the product
82.4×6=494.4
2. The other factor is reduced by two times, so is the product
494.4÷2=247.2
3. A: the product is 247.2

Given that a and B are reciprocal, what is the result of 4 / a divided by 9 / b

It is known that a and B are reciprocal, 4 / a divided by 9, and the result of B is (36)
If a and B are reciprocal, then AB = 1
4/a÷b/9
=4/a×9/b
=(4×9)/ab
=36

Given that a and B are reciprocal to each other, what is the result of 3 / a × 6 / b?

3 / a × 6 / b = AB / 18 = 1 / 18
one-eighteenth

It is known that a and B are reciprocal to each other, then the calculation result of a / B is ()

A and B are reciprocal, ab = 1
a/2÷3/b=ab/6=1/6
