In a multiplication, if one factor is increased by 5, the product is increased by 100. If the other factor is increased by 4, the product is increased by 120 Can you directly divide 100 by 5 to get 20, and then divide 120 by 4, the answer is 600

In a multiplication, if one factor is increased by 5, the product is increased by 100. If the other factor is increased by 4, the product is increased by 120 Can you directly divide 100 by 5 to get 20, and then divide 120 by 4, the answer is 600

That's what you did
100 △ 5 = 20 is a factor
120 △ 4 = 30 is another factor
So it's 600

A multiplication formula, a factor multiplied by 20, to multiply the product by 120, how should the other factor change?

A multiplication formula, a factor multiplied by 20, to multiply the product by 120, the other factor should be: 6

1 / 6 + 1 / 6 + 1 / 6 + +When a = 120, the result is ()
1 / 6 + 1 / 6 + 1 / 6 + +When a = 120, the result is ()
() 20 = 3 / 5 = 1.5: () = ()% = () discount
