Explicație pas cu pas:

A

24 m : 2 + 3 hm x 2 + 5 m + 10 m + 3 hm x 2 + 50 m + 24 hm : 3 + 800 m - 20 dam

= 12 m + 6 hm + 15 m + 6 hm + 50 m + 8 hm + 800 m - 20 dam

= 12 m + 600 m + 15 m + 600 m + 50 m + 800 m + 800 m - 200 m

= 2677 m

B

85 dam : 5 + 79 dm x 10 + 79 dm x 10 + 146 dam : 2 + 200 m + 200 m + 5900 mm x 10

= 17 dam + 790 dm + 790 dm + 73 dam + 200 m + 200 m + 59000 mm

= 170 m + 79 m + 79 m + 730 m + 200 m + 200 m + 59 m

= 1517 m

______________

traseul A este mai lung decat traseul B cu 1160 m

2677 m - 15717 m = 1160 m

Answer 2

Răspuns:

Explicație pas cu pas:

A)

12m+300mx2+15m+300mx2+50m+800m+800m-200m

= 12m+600m+15m+600m+50m+800m+600m

= 12m+15m+50m+ 1200m+1.400m

= 77m+2.600m= 2.677m

-

B)

850m:5 +79m+79m +1.460m:2+200mx2+59m

= 170m+158m+730m+400m+59m

= 328m+1.130m +59m

= 1.458m+59m=1.517 m

2.677m- 1.517m= 1.160 m (traseul A este mai lung cu 1.160m)
