Answer 1

1. 4 5/15 × 15/16 : 1/24
   = 65/15 x 15/16 x 24
   = 65/16 x 24
   = 195/2
   = 97 1/2

2. 24 : 2 2/8 × 4/5 - 1/5 + 2 1/4
   = (24 : 18/8 x 4/5) - 1/5 + 9/4
   = (24 x 8/18 x 4/5) - 1/5 + 9/4
   = 128/3 - 1/5 + 9/4
   = 2560/60 - 12/60 + 135/60
   = 2683/60
   = 44 43/60

3. 2 5/8 + 11/12 × 1 5/6 : 3/9 - 1 1/3
   = 21/8 + (11/12 x 11/6 x 9/3) - 4/3
  = 21/8 + 121/24 - 4/3
  = 63/24 + 121/24 - 32/24
  = 152/24
  = 6 8/24
  = 6 1/3

semoga membantu :)

Answer 2

1.4 5/15 *15/16 : 1/24
=  4 75/240 : 1/24
=  4 75/240 * 24/1
= 4 1800/240
di perkecil menjadi = 4 225/30

2. 24 : 18/8 * 4/5 - 1/5 + 9/4
=  24 : 72/40 - 49/20
=  24 : -908/40
=  24 * 40/-908
= -960/908

3. 21/8 + 11/12 * 11/6 * 3/1 - 4/3
=  21/8 + 11/12 * 33/6 - 4/3
= 21/8 + 363/72 - 4/3
= 552/72 - 4/3
= 448/72
semoga benar jawaban ini..........................!
