What is the percentage?

The Latin term "per centum," which signifies "by the hundred," is where the word "percentage" originally came from. With 100 as the denominator, percentage are fractions. To put it another way, it's the relationship here between component and a whole, in which the value of the whole is always assumed to be 100. A specific portion or amount in each hundred is referred to as the percentage. The fraction is denoted by the sign "%," and its denominator is 100.

Finding the proportion of a whole in units of 100 is the goal of percentage calculations. There are two methods to calculate a percentage:

Through the unitary approach.
By making 100 the new denominator of the proportion.

An airline allows each passenger 33 kilograms of luggage. Carl has to lower the weight of his suitcase by 25% to stay within the limit. How much did the suitcase originally weigh?

Answers

Answer:

44 kg.

Step-by-step explanation:

The weight limit of the luggage = 33 kg

Let the original weight of the suitcase = x kg

Now, it has been given that Carl has to lower the weight of his suitcase by 25% to stay within the limit.

It means that if we decrease the original weight of the suitcase by 25% then it should be equal to 33 kg.

Thus, we have the equation

$x-0.25x=33$

Solve the equation

$0.75x=33\n\nx=(33)/(0.75)\n\nx=44$

Therefore, the original weight of the suitcase was 44 kg.

1- 0.25= 0.75 (multiplier)

33÷0.75=44

The suitcase originally weighed 44kg

Hope this helps!

A van travels 220 miles on 10 gallons of gas. Find how many gallons the van needs to travel 550 miles.31 gallons of gas
121 gallons of gas
25 gallons of gas
115 gallons of gas

Answers

The van will need 25 gallons of gas for it to travel 550 miles. This is calculated by dividing 10 gallons to 220 miles to get the miles per gallons, which in this case is 22 miles per gallon. Then we have to divide 550 miles by 22 miles per gallon to get the total gas consumption, which is 25 gallons.

Answer:

Step-by-step explanation:

To calculate how many gallons the van needs to travel 550 miles you should multiply the number of miles by the relationship between the number of gallons of gas it needs to travel 220 miles, (it is important to put the quantity in miles on the denominator) as follows:

$550miles*(10gallons)/(220miles)=25$

Therefore the van needs 25 gallons of gas to travel 550 miles
