5 * 6 = 30
30 is between 24 and 34
12:8 can also be written as

To find the percent you have to do 12÷8 and that equals 1.5, then you have to do 1.5×100 and that equals 150. The ratio, 12:8 as a percent is 150%
Answer:
The number of (2 X 4 ) foot tiles needed for 48 square feet is 6.
Step-by-step explanation:
The dimensions of the small tiles = 2 ft x 4 ft
Area that needed to be covered by tiles = 48 sq feet
Now, Area of 1 tile = LENGTH X WIDTH
= 2 ft x 4 ft = 8 sq ft
Now, 
= 
or, Number of tiles required = 6
Hence, the number of (2 X 4 ) foot tiles needed for 48 square feet is 6.
