$\it d)\ \ =\dfrac{\ 360^{(180}}{180}=\dfrac{2}{1}=2$

Answer 2

Răspuns:

Explicație pas cu pas:

1/2 = 1 supra 2, unde / = linie de fracție

a) (1/2) × (4/5) × 15/2 = (1×4×15)/(2×5×2) = 60/20 = 3

60/20 se simplifică cu 20 ⇒(60:20)/(20:20) = 3/1=3

b)  (4/21) × (7/2) × (3/5) = (4/2) ×(7×3)/21  × 1/5 = 2×(21/21)×1/5 = 2/5

_____________________________________________________

c)  (3/4) ×(2/33) × (7/3) = 7/(2×33) = 7/66

3/3 = 1;  2/4 = 1/2

________________________________

d)  (24/15) × (5/6) × 3/2 = 24/(6×2)  × (5×3)/15 = 2 × (15/15) = 2×1 = 2
