What is the equivalent decimal to this fraction? 10/45 0.2 0.222222222... 0.232323232323... 0.181818181818...

Ivan

Factorize the numerator and denominator, then simplify:

10/45 = (2×5)/(9×5) = 2/9

Now,

1/9 = 1/10 + 1/90

1/90 = 1/10 × 1/9 = 1/10 × (1/10 + 1/90) = 1/100 + 1/900

1/900 = 1/100 × 1/9 = 1/100 × (1/10 + 1/90) = 1/1000 + 1/9000

and so on, which is to say

1/9 = 1/10 + 1/100 + 1/1000 + …

1/9 = 0.111…

so that multiplying both sides by 2 gives

2/9 = 0.222…

Billie Holiday sells children's clothing for Sara Vaughn's Toddler Shop. Baby blankets sell for $29.99 after a markup rate based

Mariulka [41]

Answer:

Cost: $14.349

Markup: $15.649

Step-by-step explanation:

1. Rewrite the percent as decimal. Divide it by 100, as following:

109/100=1.09

3. Now, knowing that Baby blankets sell for $29.99 after a markup rate based on cost of 109%, you can write the following expresion:

$x+1.09x=29.99$

Where x is the cost.

4. You must solve for x, then, you obtain:

$2.09x=29.99\\x=\frac{29.99}{2.09}\\x=14.349$

5. The markup is:

$M=29.99-14.349=15.649$
