Answer:
do we have to solve it or what cause I'm confused
Step-by-step explanation:
1. 9/11 + 2/3 = 1 16/33
2. 9/11 - 2/3 = 5/33
3. 9/11 * 2/3 = 6/11
4. 9/11 (division) 2/3 = 1 5/22
1. 8/9 + 4/7 = 1 29/63
2. 8/9 - 4/7 = 20/63
3. 8/9 * 4/7 = 32/63
4. 8/9 (division) 4/7 = 1 5/9
1. 1/6 + 2/18 = 5/18
2. 1/6 - 2/18 = 1/18
3. 1/6 * 2/18 = 1/54
4. 1/6 (division) 2/18 = 1 1/2
1. 3/4 + 2/3 = 1 5/12
2. 3/4 - 2/3 = 1/12
3. 3/4 * 2/3 = 1/2
4. 3/4 (division) 2/3 = 1 1/8
