Question

c)49/15×25/14×6/35
d)3÷4/3
e)2/3÷6
f)3/5÷1/3
g)8+3×1/5
h)7-3×(5/6-2/3)​

Answer 1

Resposta:

a) 5/3 x 2/7 = 10/21

b)5/3 ÷ 2/7 = 5/3 x 7/2 =35/6

c)49/15 x 25/14 x 6/35 = 7.350/7.350

d)3 ÷4/3 = 3 x 3/4 = 9/12 divida por 3 =3/4

e)2/3 ÷ 6 = 2/3 x 6 = 12/6 divida por 2 ficara=6/3 e se você dividir por 6=2/1

f)3/5 ÷ 1/3 = 3/5 x 3/1 = 9/5

g)8 + 3 x 1/5 = 11/55

h)7-3x (5/6 - 2/3)=

  7-3    x  3/3=

     4 x 3/3=12/12
