Studdy Solution

STEP 1

What is this asking? We need to rewrite 0.8 ounces, the amount of detergent in one laundry pod, as a simplified fraction and as a percentage. Watch out! Don't forget to simplify the fraction fully and remember how decimals relate to percentages!

STEP 2

1. Convert the decimal to a fraction.
2. Simplify the fraction.
3. Convert the decimal to a percentage.

STEP 3

Alright, let's **kick things off** by turning our decimal, 0.80.8, into a fraction.
Remember, the first place after the decimal point is the tenths place.
So, 0.80.8 is the same as **eight-tenths**, which we can write as the fraction 810\frac{8}{10}.

STEP 4

Now, time to **simplify**!
Both **8** and **10** are divisible by **2**.
So, we divide both the **numerator** (the top number) and the **denominator** (the bottom number) by **2**.
This gives us 810=8÷210÷2=45\frac{8}{10} = \frac{8 \div 2}{10 \div 2} = \frac{4}{5}.
Can we simplify further?
Nope! **4** and **5** have no common factors other than **1**.
So, our simplified fraction is 45\frac{4}{5}.
Boom!

STEP 5

To turn our decimal, 0.80.8, into a percentage, we **multiply** it by **100**.
Remember, "percent" literally means "per hundred".
So, 0.8100=800.8 \cdot 100 = 80.
This means 0.80.8 is the same as **80%**.
Don't forget to add the percent sign!

STEP 6

0.80.8 ounces of detergent is equal to 45\frac{4}{5} of an ounce, which is also equal to 8080% of an ounce.
