Question

calcule as subtrações abaixo, simplificando o resultado quando possivel. a) 3/2-2/3. b)4/6-1/3. c) 5/6-3/4. d)1/2-1/3-1/6

Answer 1

a)

3/2 - 2/3 = 9/6 - 4/6 = 5/6

b)

4/6 - 1/3 = 2/3 - 1/3 = 1/3

c)

5/6 - 3/4 = 20/24 - 18/24 = 2/24 = 1/12

d)

1/2 - 1/3 - 1/6 = 18/36 - 13/36 - 6/36 = 5/36 - 6/36 = -1/36

Answer 2

a)

3/2 - 2/3

mmc(2,3)=6

9/6-4/6=5/6

b)

4/6 -1/3

mmc(3,6)=6

4/6-2/6=2/3 ÷2= 1/3

c)

5/6-3/4

mmc(6,4)=12

10/12-9/12=1/12


d)

1/2 - 1/3 - 1/6

mmc(2,3,6)=6

3/6-2/6-1=0

Bons Estudos :)
