Answer:
A (6/9) and D (4/6)
Step-by-step explanation:
(A) HCF of 6 and 9 is 3, therefore you can divide both numbers in the fraction by 3, leaving 2/3.
(B) 5 and 7 are both prime therefore that is the simplest form of that fraction.
(C) HCF of 4 and 6 is 2, therefore you can divide both numbers in the fraction by 2, leaving 2/3.
(D) HCF of 12 and 36 is 12, therefore you can diviDr both numbers in the fraction by 12, leaving 1/3
