The product of two numbers is 70. One factor is expanded to 100 times of the original, and the other is reduced by one tenth. The product is 70
70×100÷10=700
The product of two numbers is 70. One factor is expanded to 100 times of the original, and the other factor is reduced to one tenth of the original. What is the product?
The product of the two numbers is 70. One factor is expanded to 100 times the original one, and the other factor is reduced by one tenth
It's 700
The product of two numbers is 70. One factor is expanded by 100 times, and the other factor is reduced by 10 times______ ．
According to the change law of the product, the product of two numbers is 70. If one factor is expanded by 100 times and the other factor is reduced by 10 times, the product will be expanded by 100 △ 10 = 10 times and 70 × 10 = 700
