Question

Oblicz.
a) 3,4 - 3/4; 3,5 - 3/5; 3,6 - 3/6=
b) 0,6 - 3/6;
0,7 - 2/7; 0,8 - 1/8=
2.Oblicz w pamięci
a) 0,2 * 0,02 *0,002=
b) 0,001*0,3*0,12=

Answer 1

A)3,4-3/4=34/10-3/4=68/20-15/20=53/20=2 i 13/20

3,5-3/5==35/10-3/5=70/20-12/20=58/20=2 i 18/20=2 i 9/10

3,6-3/6=36/10-3/6=108/30-15/30=93/30=3 i 3/30=3 i 1/10

b)0,6-3/6=6/10-3/6=18/30-15/30=3/30=1/10

0,7-2/7=7/10-2/7=49/70-20/70=29/70

0,8-1/8=8/10-1/8=32/40-5/40=27/40

Oblicz w pamięci:
a)0,2*0,02*0,002=0,000008

b)0,001*0,3*0,12=0,000036

Answer 2

A) 3,4 - 3/4 = 3 4/10 - 3/4 = 3 8/20 - 15/20 = 2 28/20 - 15/20 = 2 13/20 
3,5 - 3/5 = 3 5/10 - 3/5 = 3 5/10 - 6/10 = 2 15/10 - 6/10 = 2 9/10
3,6 - 3/6 = 3 6/10 - 3/6 = 3 36/60 - 30/60 = 3 6/60 = 3 1/10 

b) 0,6 - 3/6 = 6/10 - 3/6 = 36/60 - 30/60 = 6/60 = 1/10
0,7 - 2/7 = 7/10 - 2/7 = 49/70 - 20/70 = 29/70 
0,8 - 1/8 = 8/10 - 1/8 = 32/40 - 5/40 = 27/40 

zadanie 2
a) 0,2 * 0,02 * 0,002 = 0,000008
b) 0,001 * 0,3 * 0,12 = 0,001 * 0,036 = 0,000036
