X•(2 2/3 • 1 7/8 - 7/12 :14)=1/4

Answer 1

X•(2 intregi 2/3 • 17/8 - 7/12 :14)=1/4

x×(2×3+2 totul supra/3 × 17/8 -7/12 :14/1)=1/4

x×(8/3 ×17/8 -7/12 ×1/14)=1/4

x×(1×17 totul supra/3×1 - 1×1 totul supra/12×2)=1/4

x×(17/3 -1/24)=1/4

x× 8×17-1 totul supra/24 =1/4

x×135/24=1/4

x=1/4 :135/24

x=1/4 ×24/135

x=1×6 totul supra /1×135

x=6/135 simplificat cu 3
