Question

length of breadth of the floor of a room are 5m and 3 m respectively. forty tiles each with area 1/16 m2 are used to cover the floor partially find the ratio of the tiled and the non-tiled portion of the floor.​

Answer 1

Answer:

1:5

Step-by-step1: explanation:

area of floor:5*3=15m^2

area of tile=1/16 m^2

area covered by total area=(1/16) *40

                                            =5/2 m^2

total area which is not covered is =15-5/2

                                                       =25/2

ratio is=(5/2)/(25/2)

``          =1:5
