The product of two numbers is - 1, one of which is negative seven and two fifths, and the reciprocal of the other is ()

a*b=1
a=1/b
So the reciprocal of another number is this number
That's minus seven and two fifths

The product of two numbers is 3 and 1 / 3. One of the factors is exactly the reciprocal of the product. What is the other factor?
The answer is 9 and 55 / 81, 3 and 1 / 9 divided by (1 divided by 3 and 1 / 9)

3 and 1 / 3 = 4 / 3
4 / 3 to 3 / 4
One of them is 3 / 4
So let another number be X
3/4*X=4/3
X=16/9
The other is 16 / 9
Or 1 and 7 / 9

-The reciprocal of 1.4 is the multiplication of five numbers. If the product is negative, then the number of negative factors is
Do me a favor

It's - five out of seven
One or three or five
