Calculati
1/2 + 2/3 =
7/4 - 1/3 =
24/5 • 25/16 =
9/10 : 15/2 =
dau coroana

Answer 1

Răspuns:

Salut!

³⁾1/2 + ²⁾2/3 = 3/6 + 4/6 = 7/6

³⁾7/4 - ⁴⁾1/3 = 21/12 - 4/12 = 17/12

24/5 × 25/16 = 24 × 5/16 = 3 × 5/2 = 15/2 = 7,5

9/10 : 15/2 = 9/10 × 2/15 = 9/5 × 1/15 = 3/5 × 1/5 = 3/25

Answer 2

1.1/2+2/3=1/2×3+2/3×2=3/6+4/6=7/6

2.7/4-1/3=7/4×3-1/3×4=21/12-4/12=17/12

3.24/5×25/16(simplifici 25 cu 5 la 5(25:5 si 5:5))=24/1×3/16(24 si 16 la 8(24/8 si 16/8))=3/1×3/2=9/2( simplificata)

4.9/10 : 15/2=9/10×2/15(simplifici 2 cu 10 la 2, 9 cu 15 la 3)=3/5×1/3=3/15=1/5
