1) ½ + 0,5 + ¾ = …. ?2) ⅝ – ⅔ = …. ?​

1/2 + 0,5 + 3/4

= 1/2 + 5/10 + 3/4

= 1/2 + 1/2 + 3/4

= 2/4 + 2/4 + 3/4

= (2 + 2 + 3)/4

= 7/4

= 1 3/4

____

5/8 – 2/3

= (5 × 3)/(8 × 3) – (2 × 8)/(3 × 8)

= 15/24 – 16/24

= -1/24

Jawaban:

1. 1/2 + 0,5 + 3/4 = 0,5 + 0,5 + 0,75

= 0,85

2. 5/8 – 2/3= 0,625 – 0,666

= -0, 041
