100cm=1m How many square cm = one square meter?
6 1/8 - x = 1 7/8 ?
would that be 4 1/8
Thank you so much for your help.
To find out how many square centimeters are in one square meter, we need to convert the units. We know that 1 meter is equal to 100 centimeters.
Now, since we are dealing with square units (square centimeters and square meters), we need to square these conversion factors as well.
So, 1 square meter is equal to (100 centimeters) * (100 centimeters), which is equal to 10,000 square centimeters.
Therefore, there are 10,000 square centimeters in one square meter.
Regarding the second question, let's solve the equation step by step:
6 1/8 - x = 1 7/8
First, let's find a common denominator for the fractions involved. The common denominator for 8 and 8 is 8.
So, we have:
6 1/8 - x = 1 7/8
To subtract fractions, we need the denominators to be the same. Since the denominators are already the same, we can subtract the numerators:
49/8 - x = 15/8
Now, we need to isolate the variable x. To do that, we can subtract 49/8 from both sides of the equation:
- x = 15/8 - 49/8
- x = (15 - 49)/8
- x = -34/8
Now, let's simplify the fraction -34/8 by dividing both the numerator and denominator by their greatest common divisor, which is 2:
- x = -17/4
So, the solution to the equation is x = -17/4, which can also be written as -4 1/4 or -4.25.
Therefore, 6 1/8 - x is equal to 1 7/8 subtracted from 6 1/8, which is indeed equal to 4 1/8 or 4.125.
