Answer 1

☆Solusi☆

[tex] \frac{7}{4} \div \frac{9}{4} = \frac{7}{4} \times \frac{4}{9} = \frac{28}{36} = \frac{7}{9} [/tex][tex] \frac{7}{9} + \frac{4}{3} = \frac{7}{9} + \frac{12}{9} = \frac{19}{9} [/tex][tex] = 2 \ \frac{1}{9} [/tex]

opsi = b

I wish you a happy birthday ^_^

Answer 2

Verified answer

[tex]{\sf{1.) \: 1 \: \frac{3}{4} \: \div \: 2 \: \frac{1}{4} \: + \: 1 \: \frac{1}{3} }}[/tex]

[tex]{\sf{ = \: (\frac{7}{4} \: \times \: \frac{9}{4}) \: + \: \frac{4}{3} }}[/tex]

[tex]{\sf{ = \:( \frac{7}{4} \: \times \: \frac{4}{9} ) \: + \: \frac{4}{3} }}[/tex]

[tex]{\sf{ = \: (\frac{7 \: \times \: 4}{4 \: \times \: 9} ) \: + \: \frac{4}{3} }}[/tex]

[tex]{\sf{ = \: \frac{{\cancel{28}}}{{\cancel{36}}} \: + \: \frac{4}{3} }}[/tex]

[tex]{\sf{ = \: \frac{7}{9} \: + \: \frac{4}{3} }}[/tex]

[tex]{\sf{ = \: \frac{(9 \: \div \: 9) \: \times \: 7 \: + \: (9 \: \div \: 3) \: \times \: 4}{9} }}[/tex]

[tex]{\sf{ = \: \frac{(1 \: \times \: 7) \: + \: (3 \: \times \: 4)}{9} }}[/tex]

[tex]{\sf{ = \: \frac{7 \: + \: 12}{9} }}[/tex]

[tex]{\bf{ = \: \frac{19}{9} }}[/tex]

[tex]\boxed{\sf{{ \bf{ = \: \boxed{\sf{{ \bf{ 2 \: \frac{1}{9} \: \longmapsto \: (b.) }}}}}}}}[/tex]
