Myesha has a coin collection. She keeps 4 of the coins in her box, which is 5% of the collection. How many total coins are in her collection?
Multiply/scale up to solve.
If 4 coins represent 5% of the collection, then we can set up the following proportion:
4/0.05 = x/100
Where x is the total number of coins in the collection. To solve for x, we can cross-multiply:
0.05x = 400
x = 400/0.05
x = 8,000
Therefore, there are 8,000 coins in Myesha's collection.
4800 people attended a football game. If 10% of the people who attended were teenagers, how many teenagers attended the game?
Divide/scale down to solve for the missing percent.
To find out how many teenagers attended the game, we need to multiply the total number of attendees (4,800) by the percentage of teenagers who were there (10%).
10% can be expressed as a decimal by dividing by 100 or moving the decimal point two places to the left.
10% = 0.1
So, to find out how many teenagers attended:
0.1 x 4,800 = 480
Therefore, 480 teenagers attended the football game.
Bob's Gift Shop sold 800 cards for Mother's Day. One salesman, Montraie, sold 10% of the cards sold for Mother's Day. How many cards did Montraie sell?
Insert the values given in the problem then scale up or down to find the missing value.
To find out how many cards Montraie sold, we need to multiply the total number of cards sold (800) by the percentage of cards Montraie sold (10%).
10% can be expressed as a decimal by dividing by 100 or moving the decimal point two places to the left.
10% = 0.1
So, to find out how many cards Montraie sold:
0.1 x 800 = 80
Therefore, Montraie sold 80 cards for Mother's Day.
All students in Ridgewood Junior High School either got their lunch in the school cafeteria or brought it from home on Tuesday. 5% of students brought their lunch. 49 students brought their lunch. How many students in total are in Ridgewood Junior High School?
We can use a proportion to solve this problem.
Let x be the total number of students in Ridgewood Junior High School.
We know that 5% of students brought their lunch, which means that 95% of students got their lunch in the school cafeteria.
So we can set up the following proportion:
5% of x = 49
or
0.05x = 49
To solve for x, we can divide both sides of the equation by 0.05:
x = 49 ÷ 0.05
x = 980
Therefore, there are 980 students in Ridgewood Junior High School.
A group of friends were working on a student film that had a budget of $1400. They used 23% of their budget on equipment. How much money did they spend on equipment?
To find out how much money was spent on equipment, we need to multiply the total budget ($1400) by the percentage of the budget that was used on equipment (23%).
23% can be expressed as a decimal by dividing by 100 or moving the decimal point two places to the left.
23% = 0.23
So, to find out how much money was spent on equipment:
0.23 x $1400 = $322
Therefore, the group of friends spent $322 on equipment for their student film.
