Question

1. Wykonaj działanie:
1i 5/9 : 1 i 1/3 : 0,75 =
3 i 4/9 - 1 i 2/3 * 1,8 =
3 i 1/3 - 1/3 * 0,6 =
4,5 * 5 i 5/9 +6,4 * 3/8 =
Prosze pomóżcie ale nie wyniki tylko obliczenia dam naj ;D

Answer 1

1i 5/9 : 1 i 1/3 : 0,75 =14/9 : 4/3 : 75/100 = 14/9*3/4*100/75 = 14/9*25/25 = 14/9 * 1 = 14/9 = 1 5/9
3 i 4/9 - 1 i 2/3 * 1,8 = 31/9-5/3*18/10 = 31/9 - 6/2 = 62/18 - 54/18 = 8/18 = 4/9
3 i 1/3 - 1/3 * 0,6 = 10/3-1/3*6/10=10/3-6/30=100/30-6/30 = 94/30 = 3 4/30 = 3 2/15
4,5 * 5 i 5/9 +6,4 * 3/8 =45/10*50/9+64/10*3/8 = skracamy= 5/1*5/1+8/10*3/1 = 25/1+24/10 = 250/10+24/10=274/10 = 27 4/10 = 27 2/5

Answer 2

1 5/9:1 1/3:0,75=14/9:4/3:75/100=14/9*3/4:75/100=7/6*100/75=350/225=1 125/225=1 5/9

3 4/9-1 2/3*1,8=31/9-5/3*18/10=31/9-3=31/9-2 9/9=31/9-27/9=4/9

3 1/3-1/3*0,6=10/3-1/3*6/10=10/3-1/5=50/15-3/15=47/15=3 2/15

4,5*5 5/9+6,4*3/8=45/10*50/9+64/10*3/8=25+12/5=24 5/5+12/5=125/5+12/5=137/5=27,4
