Hey there! :D

A dollar bill is worth 100 pennies. 

$1.00-> .01*100 <=== same thing

When written in decimal format, each penny can be written as 100:1, because there are 100 pennies in a dollar. One penny would just be one out of 100. 

I hope this helps!

A dollar bill is equal to 100 pennies. Similarly, 100 pennies is equal to a dollar.

If we want to find the value of a penny in decimal form, we must set the following equation, using the left side to represent pennies and the right side to represent dollars (this equation cannot exist, but does anyway for the sake of this question):

100 = 1

We want to get the left side to equal 1, so we divide both sides by the value of the left side:

1 = \frac{1}{100}

Solve the fraction and turn it into a decimal:

1 \div 100 = 0.01

This would mean that a penny is worth 1%, or 0.01 of a dollar.

The ratio that would fit this question is 100:0.01.

I don't quite understand the LCD and the unlike denominators properly. May someone explain it, please.
Whitepunk [10]

Hey!

----------------------------------------------------------------------

LCD stands for Lowest Common Denominator.

----------------------------------------------------------------------

Explanation:

So let's say we have the equation 1/9 * 16/27

We want to find the LCD of both fractions. To find the LCD of both fractions find a the lowest common denominator in both fractions.

In this equation the lowest common denominator is 27 because 9 can go in 27 and 27 can go into itself. Se basically 27 is the lowest possibly common denominator both fractions can get to.

----------------------------------------------------------------------

Hope This Helped! Good Luck ;)

Ms.Waddell put a 12-inch tall bucket under a leak in her sink. The bucket fills at a constant rate of 1/2 inch in every 1/6 of a
Angelina_Jolie [31]

Answer:

4 hours

Step-by-step explanation:

To solve this question you will simply make a ratio type equation. You know that every 1/6 of an hour, or every 10 minutes, the bucket will fill 1/2 an inch. The bucket is 12 inches tall.

\frac{10 min}{1/2 inch} = \frac{x min}{12 inches}

Cross multiply

120=\frac{1}{2} x

x=240 min

Convert minutes to inches

\frac{240 min}{1}  * \frac{1 hr}{60 min} = 4 hr

Final answer: 4 hours

Hope this helps!
