Complete the patterns of equivalent ratios by filling in the gaps. 64:16
32:8
_ : _
_ : 2
4 : 1

64:16

32:8

16: 4

8:2

4:1

Step-by-step explanation:

Looking at the pattern, we have to multiply the value on the right by 4 to get the value on the left

Also, as we go down, we divide each of either sides by 2 to get the next term

in line

So we fill in the ratio as follows;

64:16

32:8

16: 4

8:2

4:1

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
