In a room at a​ museum, we want to tile the floor. If the floor measures 15 feet by 55 ​feet, what is the​ largest-size square tile that we can use to tile the floor without having to cut​ tiles? A) 11 ft by 11 ft
B) 5 ft by 11 ft
C) 5 ft by 3 ft
D) 3 ft by 3 ft
E) 11 ft by 3 ft
F) 5 ft by 5 ft

B. 5 foot by 11 foot

the numbers have to be divisible in both directions.

11x11 doesn't work, because at 15 feet wide one tile isn't wide enough, and 2 is too wide.

5x11 works- 3x5= 15 and 11x5=55. you'd use 15 tiles.

the rest are all smaller.

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.
