When two numbers are multiplied, one factor is expanded by 8 times and the other factor is reduced by half, and the product is 360, then the original product is 360________ . (with explanation)

When two numbers are multiplied, one factor is expanded by 8 times and the other factor is reduced by half, and the product is 360, then the original product is 360________ . (with explanation)

Math problem: if two numbers are multiplied, one factor is expanded by 8 times, and the other factor is reduced by half, and the product is 360, then the original product is 360_ 90_______ .
360*2÷8=90

Multiplication of a natural number by a true fraction ()
A. The product is greater than the number B. the product is less than the number C. The product is less than or equal to the number

Because the true fraction is less than 1, the product of a natural number (except 0) multiplied by the true fraction is less than the natural number. If the natural number is 0, the product of the natural number multiplied by the true fraction is 0, for example, 0 × 13 = 0; so select C

A natural number that is not equal to 0 is multiplied by the true fraction, and its product () is the original number

A natural number not equal to 0 multiplied by a true fraction, its product (less than) the original number
