Quizz1) ( ¾ + ½ ) × ⅓ = …2) 0,5 × ¾ = …

Jawab:

$displaystylett(1.)::frac{5}{12}\\(2.)::frac{3}{8}$

Penjelasan dengan langkah-langkah:

$displaystylett (1.)::frac{1}{3}left(frac{3}{4}+frac{1}{2}right)=\\frac{1}{3}left(frac{3}{4}+frac{1times2}{2times2}right)=\\frac{1}{3}left(frac{3}{4}+frac{2}{4}right)=\\frac{1}{3}left(frac{5}{4}right)=\\frac{5}{12}$

—————————

$displaystylett (1.)::0,5timesfrac{3}{4} =\\frac{5}{10}timesfrac{3}{4}=\\frac{5div5}{10div5}timesfrac{3}{4}=\\frac{1}{2}timesfrac{3}{4}=\\frac{3}{8}$

Jawaban :

1) ( ¾ + ½ ) × ⅓

= ( 3 + 2/4 ) × ⅓

= 5/4 × ⅓

= 5 × 1/4 × 3

= 5/12

2. 0,5 × ¾

= 5/10 × ¾

= ½ × ¾

= 1 × 3/2 × 4

= 3/8
