matrix ( 2/7 + 5/21 ):1 2/7 =&26:3 1 4 * 1 16 =\\ 17 36 :( 7 12 - 5 9 )=& 2 1/3 / (1 5/9) - 5/6 = matrix​

Answer 1

1)(2/7+5/21):1 4/7 ;

2/7+5/21=6/21+5/21=11/21

11/21:1 4/7=11/21×7/11=1/3

2)(8/11+3/22):5/11

8/11+3/22=16/22+3/22=19/22

19/22:5/11=19/22×11/5=19/10=1 9/10

3) 1 7/12:(3/8+5/12);

3/8+5/12=9/24+10/24=19/24

1 7/12:19/24=19/12×24/19=2

4) 17/36:(7/12-5/9);

7/12-5/9=21/36-20/36=1/36

17/36:1/36=17/36×36/1=17
