Answer 1

Resposta:

a)3×2,5-1,5==7,5-1,5=6

b)2×1,5+6=3+6=9

c)3,5×4-0,8=14-0,8=13,2

d)0,8×4+1,5=3,2+1,5=4,7

e)2,9×5-8,01=14,5-8,01 = 6,49

f)1,3×1,3-1,69 =1,69-1,69 = 0

Answer 2

Resposta:

a)3×2,5-1,5=  6,0

3x2 = 7,5-1,5 = 6,0

b)2×1,5+6=  9,0

2x1,5=3,0+6=9,0

c)3,5×4-0,8=  13,2

3,5x4=14-0,8=13,2

d)0,8×4+1,5=  4,7

0,8x4=3,2+1,5=4,7

e)2,9×5-8,01=  6,49

2,9x5=14,5-8,01= 6,49

f)1,3×1,3-1,69 = 0

1,3x1,3=1,69-1,69=0
