Ibu membeli 3/4 kg daging dan 2,5 telur berapa kg berat belanja ibu

Jawaban:

$frac{3}{4} + 2.5 = 0.75 + 2.5 =3,25 : kg$

$frac{3}{4} times frac{25}{25} = frac{75}{100} = 0.75$

$sf frac{3}{4} + 2.5$

$sf = frac{3}{4} + 2 frac{5}{10}$

$sf = frac{3}{4} + frac{2 times 10 + 5}{10}$

$sf = frac{3}{4} + frac{25}{10}$

$sf = frac{3}{4} + frac{25 div 5}{10 div 5}$

$sf = frac{3}{4} + frac{5}{2}$

$sf = frac{3}{4} + frac{5 times 2}{4}$

$sf = frac{3}{4} + frac{10}{4}$

$sf = frac{(3 + 10)}{4}$

$sf = frac{13}{4}$

$sf =3 frac{1}{4}$
