1) 0,75 * 8/15 = 3/4 * 8/15 = 24/60 = 2/5
2) 1 1/2 * 3 1/3 = 3/2 * 10/3 = 30/6 = 5
3) (1 3/5)² = (8/5)² = 64/25
4) 3/8 *24 = 3 * 3 = 9
5) 2/5 * 3/8 = 6/40 = 3/20
Відповідь:
Покрокове пояснення:
1) 3/4 * 8/15 = 2/5 =0,4
2) 3/2 * 3* 1/3 = 1/2 * 3 = 3/2 =1,5
3) (8/5)^2 = 64/25
4) 3*3 = 9
5) 1/5 * 3/4 = 3/20
