3 5/8 × 0,4 - 1 1/8 : 3/4 tolong pake caranya

Kelas 6 Matematika
Bab Pecahan

3 5/8 x 0,4 - 1 1/8 : 3/4
= 29/8 x 4/10 - 9/8 x 4/3
= 29/8 x 2/5 - 3/2
= 29/20 - 30/20
= -1/20

[tex]3 \frac{5}{8} \times 0.4 - 1 \frac{1}{8} \div \frac{3}{4} \\ = (\frac{29}{8} \times \frac{4}{10} ) - (\frac{9}{8} \times \frac{4}{3} ) \\ = \frac{29}{20} - \frac{3}{2} \\ = \frac{29}{20} - \frac{30}{20} \\ = - \frac{1}{20} [/tex]
