8) Erica chooses a number. She divides it by four then subtracts 11. She then divides this
result by two. Her answer is 12.5. What was the number she started with?

Step-by-step explanation:

Let x be the number.

Divide it by 4

x/4

Subtract 11

x/4 - 11

x-44/4

Divides this result by 2

x-44/4 ÷ 2

x-44/4 × 1/2

x-44/8

Her answer is 12.5

x-44/8 = 12.5

x-44 = 12.5 × 8

x = 100 + 44

x = 144

Hence,

She started with 144 number.

-2/

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
