P, Q and R are masses. P is the smallest and R is the biggest of the three. If P is 300g and R is ½kg which of the following is a possible mass for Q?
Q could have various possible masses, as long as it is greater than 300g and less than ½kg. Some possible masses for Q could be 350g, 400g, or 450g, among others.
To determine a possible mass for Q, we need to find a value that is greater than 300g (mass of P) and less than 500g (mass of R).
Given that R is the biggest mass, we can conclude that the mass of Q must be greater than 300g and less than 500g.
Therefore, a possible mass for Q is any value between 300g and 500g, exclusive of both endpoints.
To find a possible mass for Q, we need to find a value between the smallest and biggest masses, P and R respectively. We know that P is 300g and R is ½kg.
To compare P and R directly, we need to convert the masses to the same unit. Since there are 1000 grams in one kilogram, we can convert P to kilograms by dividing it by 1000:
P = 300g / 1000 = 0.3kg
Now we have P = 0.3kg and R = 0.5kg.
Since Q must be between the smallest and biggest masses, the possible mass for Q is any value between 0.3kg and 0.5kg, exclusive of both values.
Thus, a possible mass for Q could be 0.4kg, as it falls between 0.3kg and 0.5kg.
