Taksirlah hasil perkalian dan pembagian pecahan berikut.


a. 4 1/4 × 3 3/4 =
b. 3 4/5 × 1 1/6 =
c. 5 4/5 ÷ 3 1/6 =
d. 10 1/8 ÷ 4 5/6 =
minta bantuannya ya kak..

Jawaban:

a.4 \frac{1}{4}  \times 3  \frac{3}{4}  =  \frac{17}{4}  \times  \frac{15}{4}  =  \frac{255}{16}  = 15  \frac{15}{16}

b.3 \frac{4}{5}  \times 1 \frac{1}{6}  =  \frac{19}{5}  \times  \frac{7}{6}  =  \frac{133}{30}  = 4\frac{13}{30}

c.5 \frac{4}{5}  \div 3 \frac{1}{6}  =  \frac{29}{5}  \div  \frac{19}{6}  =  \frac{29}{5}  \times  \frac{6}{19}  =  \frac{174}{95}  = 1 \frac{99}{95}

d.10\frac{1}{8}  \div 4 \frac{5}{6}  =  \frac{81}{8} \div  \frac{29}{6}  =  \frac{81}{8}  \times  \frac{6}{29}  =  \frac{243}{116}  = 1 \frac{127}{116}

Penjelasan dengan langkah-langkah:

maaf klo salah atau kurang sederhana bilangannya
