Answer: 3:2 or 3/2
Explanation:
48 white tiles each cost £2, so you multiply each tile by 2 to find the total cost.
48 * 2 = 96
So the total cost of the white tiles is £96
16 blue tiles each cost £4, so you multiply each tile by 4 to find the total cost.
16 * 4 = 64
So the total cost of the blue tiles is £64
Now, to find the ratio, you compare the total cost of white tiles by the total cost of blue tiles.
96:64
Now, you can simply this to get the common ratio. Find a common divisor.
96 / 32 = 3
64 / 32 = 2
The ratio is 3:2 or 3/2
