4 1/2+ 1 3/5 - 3 3/4 = - Universityku

4 1/2+ 1 3/5 – 3 3/4 =

Penjelasan dengan langkah-langkah:

$4 frac{1}{2} + 1 frac{3}{5} - 3 frac{3}{4} = \ 2 frac{1 times 10}{2 times 10} + frac{3 times 4}{5 times 4} - frac{3 times 5}{4 times 5} = \ 2 frac{10 + 12 - 15}{20} = 2 frac{7}{20}$

4 1/2+ 1 3/5 – 3 3/4 = (4 + 1 – 3) + (1/2 + 3/5 – 3/4)

= 2 + (1×10/2×10 + 3×4/5×4 – 3×5/4×5)

= 2 + (10/20 + 12/20 – 15/20)

= 2 + (10 + 12 – 15 /20)

= 2 + 7/20

= 2 7/20

semoga membantu 🙂
