TolongDonk?YgBaik:) -PakaiCaaraaYaaKak ^_^ (1) 5 1/4 : 7/8 X 0,75 = (2) 7,5 : 2 1/2 X 32% = (3) 26² - 24² = (4) 100 - (-5) + (-12) X 4 = -SbelumnyaTrimakasih:)

semogaa membantu...

1.
[tex]5 \frac{1}{4} \div \frac{7}{8} \times \frac{75}{100} = \frac{21}{4} \div \frac{7}{8} \div \frac{75}{100} [/tex]
[tex] = \frac{21}{4} \times \frac{8}{7} \times \frac{75}{100} [/tex]
[tex] = \frac{3}{1} \times \frac{1}{1} \times \frac{3}{2} = \frac{9}{2} [/tex]
2.
[tex] 7.5 \div 2 \frac{1}{2} \times 32\% = \frac{75}{10} \div \frac{5}{2} \times \frac{32}{100} [/tex]
[tex] = \frac{75}{10} \times \frac{2}{5} \times \frac{32}{100} [/tex]
[tex] = \frac{3}{5} \times \frac{1}{1} \times \frac{32}{20} [/tex]
[tex] = \frac{96}{100} [/tex]
3. 26² - 24² = 676-576 = 100
[tex] \sqrt{100} = 10[/tex]
