Maya has 4 1/2m of ribbon. She uses 1 3/4m to wrap a present and 1/3m to make a bow. How much ribbon is left?
4 6/12 - (1 9/12 + 4/12) = ?
4 6/12 -1 9/12 -4/12 (the key is to distribute the negative sign through the parentheses first)
Now simplify by combining negative fractions
4 6/12 -2 1/12
answer 2 5/12
To find out how much ribbon is left, we need to subtract the amount used from the total amount of ribbon Maya had.
Maya had 4 1/2 m of ribbon.
She used 1 3/4 m to wrap a present.
She also used 1/3 m to make a bow.
First, we need to convert the mixed numbers to improper fractions.
4 1/2 m = 9/2 m
1 3/4 m = 7/4 m
Now, let's add the amounts used:
Total amount used = 7/4 m + 1/3 m
To add these fractions, we need to find a common denominator, which in this case is 12.
= (7/4 * 3/3) m + (1/3 * 4/4) m
= 21/12 m + 4/12 m
= 25/12 m
Now, to find the amount left, we subtract the amount used from the total amount Maya had:
Amount left = 9/2 m - 25/12 m
Again, we need to find a common denominator:
= (9/2 * 6/6) m - (25/12 * 2/2) m
= 54/12 m - 50/12 m
= 4/12 m
= 1/3 m
Therefore, Maya has 1/3 m of ribbon left.
To find out how much ribbon Maya has left, we'll need to subtract the lengths of ribbon she used from the total length she had.
Maya had 4 1/2m of ribbon, which is the same as 4 + 1/2 = 4.5m of ribbon.
She used 1 3/4m to wrap a present and 1/3m to make a bow.
To subtract mixed numbers, we need to find a common denominator. In this case, the common denominator of 4 and 3 is 12.
1 3/4m is the same as 7/4m, and 1/3m is the same as 4/12m.
So, Maya used a total of 7/4 + 4/12 = (21 + 4)/12 = 25/12m of ribbon.
To subtract 25/12m from 4.5m, we need to convert 4.5m to a fraction with the common denominator of 12.
4.5m is the same as 4 + 0.5 = 4 1/2, which is 9/2 when written as a fraction with a common denominator of 2.
Therefore, the total length of ribbon Maya has left is 9/2 - 25/12.
To subtract fractions, we need to find a common denominator. In this case, the common denominator is 12.
9/2 is the same as 54/12 when written with a common denominator of 12.
So, the total length of ribbon Maya has left is 54/12 - 25/12 = 29/12m.
Therefore, Maya has 29/12m of ribbon left.
To simplify the answer, we can express it as a mixed number:
29/12 is the same as 24/12 + 5/12, which is equal to 2 + 5/12.
So, Maya has 2 5/12m of ribbon left.
