ibu membeli kain selebar 4 1/5 m. 2 1/4 m dibuat baju,berapa meter sisa kain ibu?

[tex]4 \frac{1 }{5} - 2 \frac{1}{4} = \frac{39}{20} = 1.95[/tex]

[tex]4 \frac{1}{5} - 2 \frac{1}{4} [/tex]
[tex] \frac{21}{5} - \frac{9}{4} [/tex]
[tex]( \frac{21}{5} \times 4) - ( \frac{9}{4} \times 5)[/tex]
[tex] \frac{84}{20} - \frac{45}{20} [/tex]
[tex] \frac{39}{20} [/tex]
[tex] = 1 \frac{19}{20} m[/tex]
Semoga membantu ya...
