What is two different ways i could explain to a friend that 127.5 divide by 1.7 cannot have a quotient of 750.?
1) Do the actual division. 2) Do the multiplication (750 x 1.7), and see whether it is, or isn't, 127.5. 3) Do some approximations: 3a. If you divide 127.5 by a number greater than 1, the answer will always be LESS than 127.5. 3b. If you do the multiplication of 750 by a number GREATER THAN 1, you'll get a result that is greater than 750.
