Answer:

B and D

Step-by-step explanation:

So basically we have to find the unit rate of 2:4.

(remember to find the unit rate we have to simplfy the ratio until one of the quantities is 1)

2:4 (divide by 2 on each side)

1:2 (B)

now we can use this unit rate of 1:2 to find out other equal ratios

1:2 (multiply 5 on both sides)

5:10 (D)
