Question

calculeaza: 26×(370×100-100×229):100= 2×320+331×2+2×149= 2×428-2×117+2×190= 1512:54+125:5= (19500+6250):25=

Answer 1

1. 26 x (370 x 100 - 100 x 229) : 100 = 
26 x (37000 -  100 x 229) : 100 =
26 x (37000 - 22900) : 100 =
26 x 14100 : 100 =
366600 :100 =  3666

2. 2 x 320 + 331 x 2 + 2 x 149 =
640 + 331 x 2 + 2 x 149 = 
640 + 662 + 2 x 149 =
640 + 662 + 298 = 1600

3. 2 x 428 - 2 x 117 + 2 x 190 =
856 - 2 x 117 + 2 x 190 =
856 - 234 + 2 x 190 =
856 - 234 + 380 = 1002

4. 1512 : 54 + 125 : 5 =
28 + 125 : 5 =
18 + 25 = 43

5. (19500 + 6250) : 25 =
 25750 : 25 = 130
