Pertanyaannya di gambar ya.

Jawaban:

$1 .: : frac{1}{4} + frac{1}{2} + frac{3}{4} \ \ = frac{1}{4} + frac{2}{4} + frac{3}{4} \ \ = frac{6}{4} \ \ = frac{3}{2}$

$2. : : frac{3}{4} + 0.8 times 2 frac{1}{2} \ \ = frac{3}{4} + ( frac{4}{5} times frac{5}{2} ) \ \ = frac{3}{4} + frac{20}{10} \ \ = frac{15}{20} + frac{40}{20} \ \ = frac{55}{20} \ \ = frac{11}{4}$

Penjelasan dengan langkah-langkah:

1. 1/4 + 2/4 + 3/4= 6/4 = 3/2

2. 3/4 + 4/5 x 5/2

= 3/4 + (4/5 x 5/2)

= 3/4 + 20/10

= 3/4 + 2

= 3/4 + 8/4

= 11/4
