$\mathbb \color{aqua} \underbrace{JAWABAN}$

$\implies \small \boxed{ \bold{3 \frac{4}{7} }}$

------------------

$\mathbb \color{orange} \underbrace{PENYELESAIAN}$

$\sf1,25 \div 90\% \times 2 \frac{4}{7} \longrightarrow \small \boxed{ \sf ubah \: menjadi \: pecahan \: biasa}$

$\sf = \frac{125}{100} \div \frac{90}{100} \times \frac{18}{7}$

$\sf = \frac{125}{100} \times \frac{100}{90} \times \frac{18}{7}$

$\sf = \frac{125 \times 100 \times 18}{100 \times 90 \times 7}$

$\sf = \frac{225.000}{63.000} \longrightarrow \small \boxed{ \sf sederhanakan}$

$\sf = \frac{25}{7}$

$\sf = \bold{ 3 \frac{4}{7} }$

$\\ \\ \huge \color{lightgreen} \xrightarrow \textsf{\textbf{cara lain : }} \\ \\$

$\sf1,25 \div 90\% \times 2 \frac{4}{7} \longrightarrow \small \boxed{ \sf ubah \: menjadi \: pecahan \: biasa}$

$\sf = \frac{125}{100} \div \frac{90}{100} \times \frac{18}{7}$

$\sf = \frac{ \cancel{125} \: {}^{5} \: } { \cancel{100} \: { \cancel{_4} \: } {\cancel{_2}}} \times \frac{ \cancel{100} \: {}^{ \cancel{10} \: {}^{5} } }{ \cancel{90} \: \cancel{_9} \: \: } \times \frac{ \cancel{18} \: {}^{ \cancel2} }{7 \: }$

$\sf = \frac{5 \times 5}{7}$

$\sf = \frac{25}{7}$

$\sf = \bold{ 3 \frac{4}{7} }$

------------------

$\mathbb \color{red} \underbrace{KESIMPULAN}$

$\sf Jadi, hasil \: dari \: \bold{1,25 \div 90\% \times 2 \frac{4}{7} } \: adalah \: \bold{3 \frac{4}{7} }$
