Calculate the following questions. If you can simplify the calculation, please simplify the calculation. There is only one question that can be simplified. I didn't list that question, but these three questions are not simplified 1 (3 / 4 plus 1 / 3) divided by 9 / 8 x 3 / 26 2 (75% plus 2 / 7 minus 9 / 14) divided by 1 / 28 3 5.48 minus 4 out of 9 minus 10 out of 99 divided by 2 out of 11

① （3/4+1/3）÷9/8×3/26=（9/12+4/12)×8/9×3/26=13/12×8/9×3/26=1/9② （75/100+2/7-9/14）÷1/28=（3/4+4/14-9/14）×28=3/4×28-5/14×28=21-10=11③ 5.48-4/9-10/99÷2/11=5.48-4/9-10/99×11/2=5.48-4/9-...
