Question

(3/17+3/54+1/2)*(1-28):(9:6/11-148 1/4:9) =


По действиям

Answer 1

1)3/17+5/34+1/2=6/34+5/34+17/34=28/34

2)1-11/28=28/28-11/28=17/28

3)9:6/11=9/1*11/6=33/2

4)148 1/4:9=593/4*1/9=16 17/36

5)33/2-593/36=594/36-593/36=1/36

6)28/34*17/28=1/2

7)1/2:1/36=1/2*36/1=18       конечный ответ

Может присмотритесь к моей задаче? Там написано "3/17+3/54+1/2", но никак не "3/17+5/34+1/2".

(3/17 + 5/34 + 1/2) * (1 - 11/28) : (9 : 6/11 - 148 1/4 : 9) = 18;

1) 3/17 + 5/34 = 6/34 + 5/34 = (6 + 5)/34 = 11/34;2) 11/34 + 1/2 = 11/34 + 17/34 = (11 + 17) /34 = 28/34 = 14/17;3) 1 - 11/28 = 28/28 - 11/28 = (28 - 11)/28 = 17/28;4) 14/17 * 17/28 = 14 * 17/ 17 * 28 = 1/2;5) 9 / 6/11 = 9/1 * 11/6 = 9 *11 /1 * 6 = 99/6 = 33/2;6) 148 1/4 / 9 = 593/4 * 1/9 = 593 * 1/4 * 9 = 593/36; 7) 33/2 - 593/36 = 594/36 - 593/36 = (594 - 593)/36 = 1/36;8) 1/2 / 1/36 = 1/2 * 36/1 = 1 * 36/2 * 1 = 18;
