tolong bantu jawab yaa, sama pake caranya ​

1. a. 3/8 + 7/24

= 9/24 + 7/24

= 16/24 (dibagi 8 semua)

= 2/3

b. 3 4/7 - 1 3/4

= 25/7 - 7/4

= 100/28 - 49/28

= 51/28

= 1 23/28

c. 2,35 - 0,8 + 1,284

= 235/100 - 8/10 + 1284/1000

= 2350/1000 - 800/1000 + 1284/1000

= 2834/1000

= 2,834

2. a. 3/5 × 2 1/6

= 3/5 × 13/6

= 39/30 (dibagi 3 semua)

= 13/10

= 1,3

b. 8 : 1 1/4

= 8 : 5/4

= 8 × 4/5 (dibalik karena dijadikan perkalian)

= 32/5

= 6 2/5

c. 1,25 : 0,3

= 125/100 : 3/10

= 125/100 × 10/3 (dibalik karena dijadikan perkalian)

= 1250/300 (dibagi 50 semua)

= 25/6

= 4 1/6

3. ((11 1/6 + 3 2/3) - 8 1/3)) : 0,5

= ((67/6 + 11/3)) - 25/3)) : 5/10

= ((67/6 + 22/6)) - 50/6)) : 5/10

= (89/6 - 50/6) : 5/10

= 39/6 × 10/5

= 390/30

= 13
