80 km is 9% of what distance??

Karolina [17]

Answer:

80 km is 9% of 888.89 km.

Step-by-step explanation:

We know that:

80 km = 9%

Work:

80/9 km = 1%
=> 80/9 x 100 = 100%
=> 8000/9 = 100%
=> 888.89 km = 100% (Rounded to nearest hundredth)

Hence, 80 km is 9% of 888.89 km.

Hoped this helped.

In Cecilia’s CD collection, 1/5 of her Jazz CDs represents 1/10 of all her CDs. What is the ratio of her Jazz CDs to her non-Jaz

KatRina [158]

Answer: The required ratio is 1:1.

Step-by-step explanation:

Let the total number of CDs be 100

$\frac{1}{10}$ of CDs is given by

$\frac{1}{10}\times 100\\\\=10$

According to question,

$\frac{1}{5}$ of her Jazz CDs represents $\frac{1}{10}$ of all her CDs.

Let the number of Jazz CDs be x

So, it becomes

$\frac{1}{5}\times x=10\\\\x=10\times 5\\\\x=50$

So, Number of Jazz's CDs is 50

Number of Jazz non CDs is given by

$100-50=50$

Ratio of her CDs to her non- CDs is given by

$50:50\\\\1:1$

Hence, the required ratio is 1:1.
