Answer:
1/2 ÷ 4 = 8
Step-by-step explanation:
Dividing fractions is as easy as pie. Flip the second and multiply.
1/2 ÷ 4 = 1/8
A whole number secretly has a 1 underneath, like this: 4/1
Flip the second number over to get 1/4, then multiply straight across.
×
= 
Try to do the same for the other answers and see if they're right (they're not).
1/8 x 1/6 = 1/48
1/3 x 1/4 = 1/12
1/9 x 1/2 = 1/18
Primeiro multiplica o -2 com tudo que tem dentro do parenteses (chuveirinho) -114 = -5x -2(4x+18)
-2 . 4x = -8x + -2 . 18 = -36 = -8x-36
Agora soma os números com incógnitas (no caso x)
-114 = - 5x - 8x -36
Joga a incógnita do outro, tornando positiva
-114 = -13x - 36
13x -114 = -36
e o 114 do outro lado, ficando positiva também
13x -114 = -36
13x = - 36 + 114
13x = 78
x = 78 /13
x= 6
