1 2/3 * 1 4/5 = 5/3 * 9/5 = 45/15 =3
1 3/8 * 1 1/3 = 11/8 * 4/3 = 44/24 = 11/6 = 1 5/6
2 1/4 * 1 3/5 = 9/4 * 8/5 = 72/20 = 3 3/5
3 1/3 * 1 2/10 = 10/3 * 12/10 = 120/30 = 4
Odpowiedź:
1 2/3*1 4/5=( 3/3+2/3)* (5/5+4/5)= =5/3*9/5= 45/15=3
1 i 3/8 * 1 i 1/3 =(8/8+3/8)*(3/3+1/3)= =11/8*4/3=44/24=22/12=1 i 10/12= 1 i 5/6
2 i 1/4 * 1 3/5 =(8/4+1/4)*(5/5+3/5)=
=9/4*8/5=72/20=18/5=3 i 3/5
3 i 1/3 * 1 i 2/10 =(9/3+1/3)+(10/10+2/10)=
=10/3*12/10=120/30=4
