Rebecca head and maintenance of a yard of ribbon then she gave 7/20 of a yard To a friend how much does she have left
man idk
its ur mom
To find out how much ribbon Rebecca has left after giving away 7/20 of a yard, you need to subtract 7/20 from the total length of the ribbon.
Let's assume the total length of the ribbon that Rebecca had initially is 1 yard.
To calculate how much ribbon she has left:
1 yard - 7/20 yard = (20/20 yard) - (7/20 yard)
= (20 - 7)/20 yard
= 13/20 yard
Therefore, Rebecca has 13/20 of a yard of ribbon left.
To determine how much ribbon Rebecca has left after giving away 7/20 of a yard, we need to subtract the given fraction from the original length of the ribbon.
If we assume that Rebecca initially had a whole yard of ribbon, we can calculate the remaining amount using the following steps:
1. Calculate the amount Rebecca gave away:
7/20 of a yard
2. Subtract the given fraction from the original length:
1 yard - 7/20 yard
To subtract fractions, we need to find a common denominator. In this case, the lowest common denominator for 20 and 1 is also 20.
3. Convert the whole number (1) to 20/20 to have a common denominator:
20/20 - 7/20
4. Subtract the fractions:
20/20 - 7/20 = 13/20
Therefore, Rebecca has 13/20 of a yard of ribbon left after giving away 7/20 of a yard to her friend.
If you know the actual length of the ribbon in yards, you can replace the "1 yard" in the calculations to get the remaining length based on the given initial length.
