Answer is choice B) 4:4
The ratio 3:3 reduces to 1:1 when we divide both parts by 3.
Then multiply both parts of 1:1 by 4 to get to 4:4
note how 3/3 = 1 and 4/4 = 1, which helps show 3/3 = 4/4, consequently leading to 3:3 and 4:4 being equivalent ratios.
In general, the ratio 3:3 is equivalent to anything of the form x:x where x is any number you want. So for instance, if x = 7, then 3:3 is equivalent to 7:7
