Question

4 2/5:6-3/4*1 1/15= Распишите по действиям

Answer 1

4 2/5 : 6 - 3/4 * 1 1/15 = - 1/15
1) 4 2/5 : 6 = 22/5 * 1/6 = (11*1)/(5*3) = 11/15
2) 3/4 * 1 1/15 = 3/4 * 16/15 = (1*4)/(1*5) = 4/5
3) 11/15 - 4/5 = 11/15 - 12/15 = - 1/15

Answer 2

4 2/5 : 6 - 3/4 х 1 1/15 =.- 1/15.... 1) 4 2/5 : 6 = 22/5 : 6/1 = 22/5 х 1/6 = 11/15. 2) 3/4 х 1 1/15 = 3/4 х 16/15 = 12/15; 3) 11/15 - 12/15 = - 1/15.
