kak bntu jwb, pleasee
Penjelasan dengan langkah-langkah:
a
[tex] \frac{7x}{5} + \frac{4x}{5} \\ \\ = \frac{7x + 4x}{5} \\ \\ = \frac{11x}{5} [/tex]
b
[tex] \frac{8x}{3} - \frac{2x}{5} \\ \\ = \frac{(5 \times 8x) - (3 \times 2x)}{3 \times 5} \\ \\ = \frac{40x - 6x}{15} \\ \\ = \frac{34x}{15} [/tex]
c
[tex] \frac{12m}{8} \times \frac{2}{24m} \\ \\ = \frac{24m}{8 \times 24m} \\ \\ = \frac{1}{8} [/tex]
d
[tex] \frac{10m}{2} \div 4 \\ \\ = \frac{10m}{2} \times \frac{1}{4} \\ \\ = \frac{10m}{8} \\ \\ = \frac{5m}{4} [/tex]
