6,8 dikurang 25% + 21 atau per4 dikurang 1,5 = dalam pecahan biasa

6,8 dikurang 25% + 21 atau per4 dikurang 1,5 = dalam pecahan biasa

Jawaban:

$tt6.8 - 25% + frac{21}{4} - 1.5$

$tt = frac{68}{10} - frac{25}{100} + frac{21}{4} - frac{15}{10}$

$tt = frac{680}{100} - frac{25}{100} + frac{525}{100} - frac{150}{100}$

$tt = frac{655}{100} + frac{525}{100} - frac{150}{100}$

$tt = frac{1180}{100} - frac{150}{100}$

$tt = frac{1030}{100} = 10 frac{30}{100} = 10 frac{3}{10}$
