Calculation of the Number of Medium-Sized TVs

To determine the number of medium-sized TVs stored in the warehouse, we need to calculate the fraction of medium-sized TVs out of the total number of TVs.

According to the information provided, there are 1470 small-sized TVs, which constitute seven-twelfths of all the TVs stored. Additionally, two-ninths of all the TVs are medium-sized.

Let's calculate the number of medium-sized TVs:

1. Calculate the total number of TVs: - The fraction of small-sized TVs is seven-twelfths, which means that the remaining fraction represents the medium-sized and large-sized TVs. - The fraction representing the medium-sized and large-sized TVs is five-twelfths (12/12 - 7/12 = 5/12). - We can calculate the total number of TVs by multiplying the fraction representing the medium-sized and large-sized TVs by the total number of TVs stored: 5/12 * Total TVs = Total TVs - 1470.

2. Calculate the number of medium-sized TVs: - The fraction representing the medium-sized TVs is two-ninths. - We can calculate the number of medium-sized TVs by multiplying the fraction representing the medium-sized TVs by the total number of TVs: (2/9) * (Total TVs - 1470).

Let's perform the calculations:

1. Calculate the total number of TVs: - The fraction representing the medium-sized and large-sized TVs is five-twelfths. - The total number of TVs can be calculated using the equation: (5/12) * Total TVs = Total TVs - 1470.

2. Calculate the number of medium-sized TVs: - The fraction representing the medium-sized TVs is two-ninths. - The number of medium-sized TVs can be calculated using the equation: (2/9) * (Total TVs - 1470).

Please note that we don't have the exact value of the total number of TVs stored in the warehouse. To provide an accurate answer, we need the total number of TVs.
