(6класс)Вычислите:1)1/3*1 1/2;2)1/5*1 2/3;3)1/4*1 1/2;4)1/7*2 4/5;5)1/8*3 1/5;6)1/9*3 3/5

Answer 1

1) 1/3 * 1 1/2 = 1/3 * 3/2 = 1/2;

2) 1/5 * 1 2/3 = 1/5 5/3 = 1/3 ;

3) 1/4 * 1 1/2 = 1/4 * 3/2 = 3/8 ;

4) 1/7 * 2 4/5 = 1/7 * 14/5 = 2/5 ;

5) 1/8 * 3 1/5 = 1/8 * 16/5 = 2/5 ;

6) 1/9 * 3 3/5 = 1/9 * 18/5 = 2/5
