1 превидите дробь 5/6 к знаменателю 24 7/12 к знаменателю 60 11/9 к 27 2/13 к 39 2 запишите в виде десятичной дроби, приведя к знаменателю 10 1000 100 4/5 13/25 5/8 12/125 2/5 17/50 11/20 133/500

№1

А) 24 : 6 = 4;

5/6 = (5 * 4) / (6 * 4) = 20/24.

Б) 60 : 12 = 5;

7/12 = (7 * 5) / (12 * 5) = 35/60.

В) 27 : 9 = 3;

11/9 = (11 * 3) / (9 * 3) = 33/27.

Г) 39 : 13 = 3;

2/13 = (2 * 3) / (13 * 3) = 6/39.

№2

А) 10 : 5 = 2;

4/5 = (4 * 2) / (5 * 2) = 8/10 = 0,8.

Б) 100 : 25 = 4;

13/25 = (13 * 4) / (25 * 4) = 52/100 = 0,52.

В) 1000 : 8 = 125;

5/8 = (5 * 125) / (8 * 125) = 625/1000 = 0,625.

Г) 1000 : 125 = 8;

12/125 = (12 * 8) / (125 * 8) = 96/1000 = 0,096.

Д) 10 : 5 = 2;

2/5 = (2 * 2) / (5 * 2) = 4/10 = 0,4.

Е) 100 : 50 = 2;

17/50 = (17 * 2) / (50 * 2) = 34/100 = 0,34.

Ж) 100 : 20 = 5;

11/20 = (11 * 5) / (20 * 5) = 55/100 = 0,55.

З) 1000 : 500 = 2;

133/500 = (133 * 2) / (500 * 2) = 266/1000 = 0,266.
