5/8 * 3/20 = 15/160 (tutaj ksrocic nie dam rady chyba)
6/13 * 20/21 * 7/10 = 840/2730 = 84/273 = 28/91
1 ) 5/8 × 3/20 = 5× 3 / 8 ×20 = 15 / 8 × 20 = 15 / 160 = 3/32
2 ) 6 / 13 × 20/21 × 7/10 = 6×20×7 / 13 × 21 × 10 = 120 × 7 / 13 × 21 × 10 = 840 / 13 × 21 × 10 = 840 / 273 × 10 = 840 / 2730 = 4 / 13
Mam nadzieję że pomogłam : )
