Soal No. 3

[tex]= 2 \frac{3}{4}+1 \frac{5}{8}-1 \frac{1}{5} \\ \\ = \frac{11}{4}+ \frac{13}{8}- \frac{6}{5} \\ \\ = \frac{100+65-48}{40} \\ \\ = \frac{117}{40} \\ \\ =2 \frac{37}{40}[/tex]

Soal No. 4

[tex]=2,4\times2 \frac{5}{8} \\ \\ = \frac{24}{10}\times \frac{21}{8} \\ \\ = \frac{3\times21}{10} \\ \\ = \frac{63}{10} \\ \\ =6 \frac{3}{10} \\ \\ =6,3 [/tex]

Soal No. 5

[tex]=5,4\div5 \frac{4}{9} \\ \\ = \frac{54}{10}\div \frac{49}{9} \\ \\ =\frac{54}{10}\times \frac{9}{49} \\ \\ = \frac{486}{490} \\ \\ =\frac{243}{245} [/tex]
