How To Make A Dollar With Coins - Maths With Mum

A dollar can be made from any combination of coins that add up to make 100 cents. Here are some common ways to make a dollar with change:

• 100 pennies
• 4 quarters
• 10 dimes
• 20 nickels
• 3 quarters, 2 dimes and a nickel
• 2 quarters and 5 dimes

There are many other ways to make a dollar and we will look at some of the common ways below.

Below is an American one dollar bill, which we commonly refer to as a dollar or US dollar.

Each dollar is worth 100 cents and each dollar bill holds the same value as one hundred cents. A dollar is therefore the same worth as one hundred 1¢ coins combined.

Instead of carrying one hundred 1¢ coins, we can use the one dollar note.

The symbol for a dollar is ‘$’.

Since one dollar is worth 100 cents we can write:

$1 = 100¢.

There are many different ways that we can make $1. We can make a dollar by using any combination of US coins that add up to 100¢.

One way to make a dollar is to use 100 cent coins.

Another way that we can make a dollar is with ten 10¢ coins (ten dimes).

This is because each dime is worth ten cents:

10¢ + 10¢ + 10¢ + 10¢ + 10¢ + 10¢ + 10¢ + 10¢ + 10¢ + 10¢ = 100¢

10 x 10¢ = 100¢

Another way to make a dollar is to use twenty nickel coins, which are each worth 5¢.

This is because 20 x 5 = 100.

20 x 5¢ = 100¢

100¢ = $1

Another way to make a dollar is with four quarter dollar coins. Each quarter is worth 25¢.

The name ‘quarter’ helps us to remember that four quarters make a whole dollar.

25¢ + 25¢ + 25¢ + 25¢ = $1

4 x 25¢ = 100¢

100¢ = $1

Examples of Counting Amounts of Money

In the example below, we are asked to work out the total amount of money. We count any coins that we have into groups that make one dollar.

We have a $1 bill and four quarter dollar coins. The four quarter dollar coins add to make a dollar because 4 x 25¢ = 100¢.

For every 100 cents that we can make, we have made one dollar.

We have a one dollar note plus the dollar made from the four quarters.

Altogether, we have $2.

In the example below, we have two $1 bills and twenty nickels (each worth 5¢).

Twenty nickels make one dollar. Each nickel is worth 5 cents and therefore we have $1.

Altogether, we have three American dollars, $3.
