Step-by-step explanation:
3. Uncle Gino's Pizza Parlor sold 200 sausage pizzas last week. That was 80% of the total pizzas they sold. How many total pizzas did they sell last week?
Given,
Pizzas sold last week = 200
This represents 80% of total pizzas sold.
Let,
x be the total pizzas sold.
80% of x = 200
Dividing both sides by 0.8
They sold 250 pizzas last week.
4. The local pet store received a shipment of tropical fish. Seventy-five percent of the tropical fish were clown-fish. If the shipment included 60 clown-fish, how many total tropical fish were in the shipment?
Given,
Number of clown-fish in shipment = 60
This represents 75% of total shipment.
Let x be the total number of fish in shipment.
75% of x = 60
Dividing both sides by 0.75
There are 80 tropical fish in the shipment.
5. In a survey of favorite pets, 45 students said they preferred cats. This was 30% of the total number of students surveyed. How many students took the survey?
Given,
Number of students who preferred cats = 45
This represents 30% of total students surveyed.
Let, x be the number of total students surveyed.
30% of x = 45
Dividing both sides by 0.3
150 students were surveyed.
6. Kara has downloaded 250 megabytes of a file onto her computer. The screen tells her that this is 25% of the total file. How many megabytes is the file?
Given,
File downloaded = 250 MB
This represents the 25% of total size of file.
Let, x be the total size of file.
25% of x = 250
Dividing both sides by 0.25
The total size of file is 1000 megabytes.
