The area of Canada is about 10,000,000 sq. km. Of that area, 9,100,000 sq. km are land and 900,000 sq km are freshwater.
question: How many thousands of square kilometers does Canada have?
question: How many hundreds of square kilometers of Canada is freshwater?
question: Gina says that you can tell how many tens, hundreds or thousands are in a number by moving the decimal point. Is she correct? Why or why not?
Please help me with step by step details. Thanks.
I would divide 10000000 by 1000 and get 10000.
10,000,000/1,000 = 10,000
9,100,000/100 = 91,000
Gina is right. Try it. When dividing by 10 move the decimal point to the left. Since we are dividing by 1000 (for the first one) move the decimal to the left 3 places to leave 10,000.
For the freshwater, move the decimal to the left 2 places to obtain 91,000.
THANK YOU SO MUCH!!!!
To solve the first question, we need to determine how many thousands of square kilometers Canada has.
To do this, we divide the total area of Canada by 1,000, since there are 1,000 square kilometers in a thousand square kilometers.
So, 10,000,000 divided by 1,000 equals 10,000. Therefore, Canada has 10,000 thousands of square kilometers.
Now let's tackle the second question. We need to find out how many hundreds of square kilometers of Canada is freshwater.
Similarly, we divide the freshwater area by 100, since there are 100 square kilometers in a hundred square kilometers.
So, 900,000 divided by 100 equals 9,000. Therefore, Canada has 9,000 hundreds of square kilometers of freshwater.
Moving on to the third question about Gina's statement. Gina believes that you can determine how many tens, hundreds, or thousands are in a number by moving the decimal point.
Unfortunately, Gina's statement is not correct. Moving the decimal point in a number does not change the value or the number of tens, hundreds, or thousands in that number. The position of the decimal point indicates the magnitude or size of the number rather than the specific groups of tens, hundreds, or thousands.
In order to identify the groups of tens, hundreds, or thousands in a number, we need to perform some mathematical operations like division or multiplication. Simply moving the decimal point does not provide any meaningful information about the grouping of tens, hundreds, or thousands in a number.
