TAM GDZIE JEST PRZERWA OBOK ULAMKA TO TEZ SIE DO ULAMKA LICZY
POWODZENIA:-)

Answer 1

(2/3 + 1/4) : 1 5/6 + 1/2 = ( 8/12 + 3/12) : 11/6 + 1/2 = 11/12 * 6/11 + 1/2 =
= 1/2 * 1/1 + 1/2 = 1/2 + 1/2 = 2/2 = 1

[(5 1/2 - 3 1/4) : 2 1/4 + 7 5/8] : 2 7/8 =
[(5 2/4 - 3 1/4) : 9/4 +7 5/8] : 2 7/8 =
[ 2 1/4 : 9/4 + 7 5/8 ] : 2 7/8 =
[ 9/4 * 4/9 + 7 5/8] : 2 7/8 =
[ 1 + 7 5/8 ] : 2 7/8 =
3 5/8 : 2 7/8 =
29/8 : 23/8 =
29/8 * 8/23 = 
29/1 * 1/23 = 29/23 = 1 6/23
