tolong kak pr matematika jawab yg benar besok dikumpulkan plisss yg benar jangan asal jawab ya

1. 4 3/4 x 5 6/4 = 19/4 x 26/4 = 494/16 = 30 7/8

2. (7 3/8 x 6 5/4) : 7 3/2 = ( 59/8 x 29/4) : 7 3/2 = 1624/32 x 2/17 = 3248/544 = 5 33/34

3. (5/6 x 8 3/4) : 9/4 = ( 5/6 x 35/4) : 9/4 = 175/24 x 4/9 = 700/216 = 3 13/54

4. (6 3/4 : 2 6/4) x 3 1/2 = ( 27/4 x 4/14) x 3 1/2 = 108/56 x 7/2 = 756/112 = 6 3/4


semoga membantu
