an old tv is 27 inches the new tv is 42 inches.... how much bigger is the new tv that the old tv...if the odl tv has 27 inches and the new tv has 42 inches

42 - 27 = 15

15/27 = 0.55555 = 56 percent bigger

so would it be 15 inche sbigger and 56% bigger too...both of them are right right

Right.

To find out how much bigger the new TV is compared to the old TV, you can subtract the size of the old TV from the size of the new TV.

So, to calculate the difference:

Difference = Size of New TV - Size of Old TV

Difference = 42 inches - 27 inches

Difference = 15 inches

Therefore, the new TV is 15 inches bigger than the old TV.
