9/16 *1/3=
72*5/6
5/7*0,42
4 1/5 *7/10
помогите пожалуйста срочно!!!

Answer 1

5 1/13 * 0,65 = 66/13 * 65/100 = (33*5)/(1*50) = 165/50 = 330/100 = 3,3

9/16 * 1/3 = (3*1)/(16*1) = 3/16

72 * 5/6 = 12 * 5 = 60

5/7 * 0,42 = 5/7 * 42/100 = (1*6)/(1*20) = 6/20 = 3/10 = 0,3

4 1/5 * 7/10 = 21/5 * 7/10 = 147/50 = 294/100 = 2,94
