You have to flip the inequality sign. If it is less than(<) it has to become greater than(>). If it is greater than(>), it has to become less than(<). If it is less than equal to(<=), it has to become greater than equal to(>=). If it is greater than equal to(>=)., it must become less than equal to(<=).

Y=You Y=The 25th letter of the alphabet. Yx2=25x2=50 So no, you become a number greater than 40.
It depends. If you start with a positive number, then multiply by a positive greater than one and the answer is greater; multiply by 1 and the answer is the same; multiply by a number between 0 and 1 and the answer is smaller; multiply by 0 and the answer is 0; multiply by a number less than 0 and the answer is negative.
easy, just cross multiply

If you multiply your number by any number greater than 1, the result will be greater than the starting number - assuming your number is positive. If your number is negative, you need to multiply it by any number less than 1, to get a result that is greater than the original number. To get a number that is slightly greater, multiply by a number that is slightly greater than 1 (ot slightly lee than= -1).
To make the product equal to 3.2, multiply by one. To make the product greater or lesser than 3.2 multiply by a number greater or lesser than one, respectively.
the answer is 0.5
When you multiply or divide the whole equation by a negative number.
If you multiply a number by a number greater than 1, you get a result that's greater than the first number. Example: 8 x 2 = 16; 16 is greater than 8.If you multiply a number by a number less than 1, you get a result that's less than the first number. Example 1: 8 x 0.5 = 4, which is less than 8. Example 2: 8 x (-1) = -8, which is also less than 8.
