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
