Multiplying any number by zero yields the result zero !
In math, a product is the result of multiplying. Multiplication is distributive over positive and negative numbers, which means, when a negative number is multiplied by a positive number, it always yields a negative result.
The question first needs to be rewritten as an equation. This can be done as follows: nx = n/0.125 where n is any number. The first step is to divide both sides by n, to give us x=1/0.125 This can then be calculated at x=8 Thus the value of x when multiplying a number by x yields the same result as dividing that number by 0.125 is 8.
A positive number multiplied by another positive number yields a positive number. A negative number multiplied by another negative number also yields a positive number. Only multiplying a negative number by a positive number (or the other way around) yields a negative number as the product.
Call the number n. From the problem statement, (n/6) + 25 = n. Multiplying both sides by 6 yields n + 150 = 6n, or 150 = 5 n or n = 30.
-16. A negative number multiplied by a positive number always yields a negative result.
The gram atomic/molar mass of cobalt is 63.546. Multiplying this number by 0.0489 yields the answer of 3.11 grams, to the justified number of significant digits.
-3. Subtracting a negative number yields the same result as adding a positive.
8% = .08. Multiplying the 2 yields .08(280) = 2.8(8) = 22.4.
The number is 21978. 21978 when multiplied by 4 which gives the result 87912 which is in reverse order.
