Pakai caranya E dan F

Pakai caranya E dan F

Penjelasan dengan langkah-langkah:

e. $1frac{2}{3} +frac{5}{6} \=frac{5}{3} +frac{5}{6} \=frac{10+5}{6} \=frac{15}{6} =frac{5}{2}=2frac{1}{2} \$

f. $frac{4}{5}+2frac{1}{4}\=frac{4}{5}+frac{9}{4}\ =frac{16+45}{20}\ =frac{61}{20}=3frac{1}{20}$

➩ Bagian E

$sf bf tt 1frac{2}{3} + frac{5}{6}$

$sf bf tt frac{1×3+2}{3} + frac{5}{6}$

$sf bf tt frac{3+2}{3} + frac{5}{6}$

$sf bf tt frac{5}{3} + frac{5}{6}$

$sf bf tt frac{5 × 2}{3 × 2} + frac{5}{6}$

$sf bf tt frac{10}{6} + frac{5}{6}$

$sf bf tt frac{10 + 5}{6}$

$sf bf tt frac{15}{6}$

$sf bf tt frac{15 ÷ 3}{6 ÷ 3}$

$sf bf tt frac{5}{2}$

$bold{underline{boxed{green{sf bf tt 2 frac{1}{2}}}}}$

➩ Bagian F

$sf bf tt 1frac{4}{5} +2 frac{1}{4}$

$sf bf tt frac{4}{5} + frac{2 × 4 +1}{4}$

$sf bf tt frac{4}{5} + frac{8+1}{4}$

$sf bf tt frac{4}{5} + frac{9}{4}$

$sf bf tt frac{4 × 4}{5 × 4} + frac{9 × 5}{4×5}$

$sf bf tt frac{16}{20} + frac{45}{20}$

$sf bf tt frac{16 + 45}{20}$

$sf bf tt frac{61}{20}$

$bold{underline{boxed{green{sf bf tt 3 frac{1}{20}}}}}$
