A class has 12 boys and 4 girls. What is the ratio of boys to girls written as a decimal? A 0.33
B 0.75
C 3.00
D 4.00
those are the only answers I need help, please ! for my gizmo test got F in math :p

C: 3.0

Step-by-step explanation:

You can write a ratio as a fraction (12/4). Write it as a fraction then just do the math.

12/4 = 3

C: 3.00

Explanation:

The ratio of 12 boys and 4 girls is 12:4

A ratio is basically a fraction so it is just 12/4

To convert a fraction to a decimal is by dividing the numerator by the denominator.

12 / 4 = 3

Therefore, the ratio of 12 boys and 4 girls written as a decimal is 3

the answer is d

"it's not the heat, it's the humidity".   that's a partly valid phrase you may have heard in the summer, but it's actually both.   the heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature.   this has important considerations for the human body's comfort.   when the body gets too hot, it begins to perspire or sweat to cool itself off.   if the perspiration is not able to evaporate, the body cannot regulate its temperature.   evaporation is a cooling process.   when perspiration is evaporated off the body, it effectively reduces the body's temperature.   when the atmospheric moisture content (i.e. relative humidity) is high, the rate of perspiration from the body decreases.   in other words, the human body feels warmer in humid conditions.   the opposite is true when the relative humidity decreases because the rate of perspiration increases.   the body actually feels cooler in arid conditions.   there is direct relationship between the air temperature and relative humidity and the heat index, meaning as the air temperature and relative humidity increase (decrease), the heat index increases (decreases).
