Question

(8 целых 3/10-6 целых 1/5):5/11+(3/8-5/16):5/9=? помогите я не могу решить

Answer 1

(8 3/10 - 6 1/5) : 5/11 + (3/8 - 5/16) : 5/9 = 4,7325

1) 8 3/10 - 6 1/5 = 8 3/10 - 6 2/10 = 2 1/10

2) 2 1/10 : 5/11 = 21/10 : 5/11 = 21/10 * 11/5 = 231/50 = 4,62

3) 3/8 - 5/16 = 6/16 - 5/16 = 1/16

4) 1/16 : 5/9 = 1/16 * 9/5 = 9/80 = 0,1125

5) 4,62 + 0,1125 = 4,7325
