I am having a hard time figuring out if I have a piece of ribbon that is 12/5 meters long. When it idcut 17/20 meters what is the remainder
Change 12/5 to an equivalent fraction
12/5 * 4 = 48/5
48/5 - 17/5 = ???
12/5 meters = 2.4 meters
17/20 = 0.85 meters
2.4 - 0.85 = 1.55 meters left.
48/5 is not equal to 12/5
To find the remainder when a piece of ribbon is cut, you need to subtract the length of the cut from the original length. In this case, the original length of the ribbon is 12/5 meters, and it is cut by 17/20 meters.
To subtract fractions, you need to have a common denominator. In this case, the denominators are 5 and 20. To make the denominators the same, multiply the denominator of 5 by 4 (to make it 20) and multiply the numerator of 12 by 4 as well. This gives us:
12/5 = 48/20
Now we can subtract the cut length:
48/20 - 17/20 = 31/20
So, the remainder when the ribbon is cut by 17/20 meters is 31/20 meters.
