Answer:
B and D
Explanation:
12/32 (if you divide them both by three) does not equal 4/10
12/32 fully simplified is 3/8
12/32 - subtracting is not simplifying, therefore, 10/30 is not correct
12/32 - both divided by two, a common factor, is 6/16, therefore, this answer is correct
12/32 - both of them divided by three equals 4/10.7 (rounded up to the nearest tenth), therefore, 4/9 is not a correct answer
12/32 - both divided by six equals 2/5.3 (rounded down to the nearest tenth), therefore, 2/6 is not a correct answer
