Question

Oblicz a) 2/5 z 30 b) 3/8 z liczby 24 c) 4 całe i 1/2 ze 120 d) 5 całych i 3/10 liczby 90 e) 3 całe i 1/3 DAM NAJ

Answer 1

2/5 z 30 = 2/5 * 30 = 60/5 = 12
3/8 z 24 = 72/8 = 9
4 i 1/2 z 120 = 9/2 * 120 = 1080/2 = 540
5 i 3/10 z 90 = 53/10 * 90 = 4770/10 = 477
3 i 1/3 z 81 = 10/3 * 81 = 810/3 = 270

Answer 2

A)  2/5 * 30 = 60/5 = 12
b)  3/8 * 24 = 3 * 3 = 9
c)  4 1/2 * 120 = 9/2 * 120 = 9 * 60 = 540
d)  5 3/10 * 90 = 53/10 * 90 = 53 * 9 = 477
e)  3 1/3 * 81 = 10/3 * 81 = 10 * 27 = 270
