1.1,5+2,4-2,6=
2.2,2+(3/4-1/4)=
3.3,4+(3/4-1/2)=
4.4,6+24%- 1 1/2=
Jawaban:
[tex]0,32 = \frac{32}{100} = \frac{8}{25} [/tex]
1. 1.1,5+2,4-2,6 = 1,3
1,5
2,4
___ +
3,9
2,6
___ -
1,3
[tex]2)2,2+( \frac{3}{4} - \frac{1}{4} ) \\ = \frac{22}{10} + \frac{2}{4} \\ = \frac{44}{20} - \frac{10}{20} \\ = \frac{34}{20} \\ = \frac{17}{10} \\ = 1 \frac{7}{10} [/tex]
[tex]3)3,4+( \frac{3}{4} - \frac{1}{2} ) \\ = \frac{34}{10} + ( \frac{3}{4} - \frac{2}{4} ) \\ = \frac{34}{10} + \frac{1}{4} \\ = \frac{68}{20} + \frac{5}{20} \\ = \frac{73}{20} \\ = 3 \frac{13}{20} [/tex]
[tex]4)4,6+24\% - 1 \frac{1}{2} \\ = \frac{46}{10} + \frac{24}{100} - \frac{3}{2} \\ = \frac{460}{100} + \frac{24}{100} - \frac{150}{100} \\ = \frac{484}{100} - \frac{150}{100} \\ = \frac{334}{100} \\ = \frac{167}{50} \\ = 3 \frac{17}{50} [/tex]
