There are many answers including:
6/9 ÷ 4/3 = 1/2 + 0/7
6/9 x 3/4 = 1/2 + 0/7
3/4 ÷ 6/9 = 1/2 + 5/8
3/4 x 9/6 = 1/2 + 5/8
3/4 ÷ 6/9 = 2/1 – 7/8
3/4 x 9/6 = 2/1 – 7/8
6/9 x 0/7 = 4/8 – 1/2
6/9 ÷ 4/3 = 1/2 + 0/7
6/9 x 3/4 = 1/2 + 0/7
3/4 ÷ 6/9 = 1/2 + 5/8
3/4 x 9/6 = 1/2 + 5/8
3/4 ÷ 6/9 = 2/1 – 7/8
3/4 x 9/6 = 2/1 – 7/8
