Gimana selesain soal berikut 1/2+2,25-3/4

Penjelasan dengan langkah-langkah:

$frac{1}{2} + 2.25 - frac{3}{4} \ \ = frac{1}{2} + frac{225}{100} - frac{3}{4} \ \ = frac{1}{2} + frac{225 div 25}{100 div 25} - frac{3}{4}\ \ = frac{1}{2} + frac{9}{4} - frac{3}{4} \ \ = frac{1}{2} + frac{9 - 3}{4} \ \ = frac{1}{2} + frac{6}{4} \ \ = frac{1}{2} + frac{6 div 2}{4 div 2} \ \ = frac{1}{2} + frac{3}{2} \ \ = frac{1 + 3}{2} \ \ = frac{4}{2} \ \ = frac{4 div 2}{2 div 2} \ \ = frac{2}{1} \ \ = 2$
