Answer:
1/12
Step-by-step explanation:
you need to make sure that they have a common denominator before doing anything.
Find the lowest common multiple (lcm), which would be 12 (3 x 4 = 12)
So then, put 12 as both denominators, and subtract.
7/12 - 9/12 is equal to 28/12 - 27/12, because 3 miltiplied by 4 equals 12, therefore you mutiply the 7 by the 4, and 4 miltiplied by 3 equals 12, therefore you multiply the 9 by the 3.
Sorry if this is confusing, i tried explaining as best i could! Hope this helped!
Answer:
10.2
Step-by-step explanation:
We have been given that Tina designed an electric skateboard that has a speed of 4 miles per hour. Further we are given that in one hour it travels 4 miles, and in 2 hours it travels 8 miles.
We know that speed of any object can be found at any time, irrespective of it being a complete hour or a fractional hour. Therefore, speed of the electric skateboard is an example of continuous data.
The that in one hour it travels 4 miles, and in 2 hours it travels 8 miles have been given so that someone can easily confuse the speed of electric skateboard as a discrete data, but in actual speed of skateboard is a continuous data.
