nt : G bt

[tex]\LARGE {\purple { diketahui } } [/tex]

3 3/4 - 1 2/5 + 0,75

[tex]\LARGE {\purple { ditanya } } [/tex]

Hasilnya?

[tex]\LARGE {\purple { jawaban } } [/tex]

[tex] = 3 \frac{3}{4} - 1 \frac{2}{5} + 0.75[/tex]

[tex] = \frac{4 \times 3 + 3}{4} - \frac{5 \times 1 + 2}{5} + 0.75 [/tex]

[tex] = \frac{15}{4} - \frac{7}{5} + 0.75[/tex]

[tex] = (15 \div 4) - (7 \div 5) + 0.75[/tex]

[tex] = 3.75 - 1.4 + 0.75[/tex]

[tex] = (3.75 - 1.4) + 0.75[/tex]

[tex] = 2.35 + 0.75[/tex]

[tex] = 3.1[/tex]

[tex]\LARGE {\purple { kesimpulan } } [/tex]

3 3/4 - 1 2/5 + 0,75 = 3,1

310/100 di perkecil, jdi sama sama di bagi 10

310 : 10 = 31

100 : 10 = 10

jadi 31/10, kalau di ubah ke bentuk desimal hasil nya 3,1

gini bukan? maaf klo salah :)
