It is possible.
Scaling is when you multiply or divide two quantities by the same number.
You multiply or divide the first quantity by the number and then you do the same for the other quantity.
you multiply 27 times a number then you multiply 18 times a different number and see if they come out with the same answer.
Multiply the denominators to equal numbers, then multiply by the same number for the numerator. Then solve.
When you multiply a number by 1, you get the same number back. Ex. 10x1=10
five digits number when you multiply by four is the same the number when you reversed it is 21978*4 = 87912
When you multiply a number by 1, it stays the same. When you multiply a number by a number greater than 1, it increases. When you multiply a number by a number that is less than 1 (a proper fraction), it decreases.
Multiply the number by a fraction
Keep the same denominator, and multiply the numerator by the whole number.
