Examples explained
There are at least 6 ratios on this chart. Ratios like this are used in lawnmowers, chainsaws, snow blowers, etc. The amounts may change based on the type of machine you have.
One example would be the first of 32:1 is when you put 128 ounces (1gallon) of gas with 4 ounces of oil.
128/4 = 32/1
Making Lemonade
Recipes are a good of examples of using ratios in real life.
For the lemonade, 1 cup sugar to 5 cups water so if I had 2 cups of sugar I would need 10 cups of water.
1/5 = 2/10
Salsa
The ratio here is 2 jars to 5 dollars or 2:5. If I wanted to buy 1 jar it would be $2.50.
2/5 = 1/2.5
Or if I wanted to buy 4 jars it would cost $10. 2/5 = 4/10
Ribeye Steak
Many items are sold per pound. These would include meat products, fruits and vegetables, candy, carpentry nails, feed for animals, etc.
For the steak above, the ratio would be 1 pound to $14.99. So if your steak weighs 2 pounds it would cost $29.98.
1/14.99 = 2/29.98
