[tex]5 \div (\frac{1}{2} + \frac{3}{4} ) + 25\% \: - 1 \: \frac{1}{4} \: [/tex]
beserta caranya, mohon dibantu kak
Penjelasan dengan langkah-langkah:
= 5 ÷ (1/2 + 3/4) + 25% - 1 1/4
= 5 ÷ (2/4 + 3/4) + 25/100 - 5/4
= 5 ÷ 5/4 + 1/4 - 5/4
= 5 × 4/5 + 1/4 - 5/4
= 20/5 - 4/4
= 4 - 1
= 3
[tex]5 \div ( \frac{1}{2} + \frac{3}{4} ) + 25\% - 1 \frac{1}{4} \\ \\ = 5 \div ( \frac{1}{2} + \frac{3}{4} ) + \frac{25}{100} - 1 \frac{1}{4} \\ \\ = 5 \div ( \frac{1}{2} + \frac{3}{4} ) + \frac{1}{4} - \frac{5}{4} \\ \\ = 5 \div ( \frac{2 + 3}{4} ) + \frac{1}{4} - \frac{5}{4} \\ \\ = 5 \div \frac{5}{4} + \frac{1}{4} - \frac{5}{4} \\ \\ = (5 \times \frac{4}{5} ) + \frac{1}{4} - \frac{5}{4} \\ \\ = \frac{20}{5} + \frac{1}{4} - \frac{5}{4} \\ \\ = \frac{80 + 5 - 25}{20} = \frac{60}{20} = \frac{6}{2} = 3[/tex]
