We can find the answer by comparing the sides of the triangles!
We are trying to find a triangle where the ratios are the same: 4/9 has to equal another fraction.
Triangle D is correct because 12/27=0.4 which is equal to 4/9=0.4
another way we can check is by seeing how much 4 is multiplied to get to twelve and seeing how much 9 is multiplied to get to 27
4*3=9
9*3=27
by this we can confirm the fractions of 4/9 and 12/27 are equal because both 4 and 9 are multiplied by the same number to get to the new fraction numbers.
