A times b equals 400. If a times 3, what's the product? If B divided by 5, what's the product?

A times b equals 400. If a times 3, what's the product? If B divided by 5, what's the product?

A times b equals 400
ab=400
a=400/b
b=400/a
If a is multiplied by 3, the product is 1200 / B, and if B is divided by 5, it is 80 / A
