Marcella bought 12/14 yards of ribbon. She uses 2 1/2 yards of ribbon for gift packages and 3 2/3 yards to tie balloons. How many yards of ribbon does Marcella have left?

6 1/12 yd

Step-by-step explanation:

The correct question is

Marcella bought 12 1/4 yards of ribbon. She uses 2 1/2 yards of ribbon for gift packages and 3 2/3 yards to tie balloons.

How many yards of ribbon does Marcella have left?

we know that...

To find out how many yards of ribbon Marcella has left, add up the yards of ribbon used for the gift packages plus the yards of ribbon used to tie the balloons. and subtract this result from the total yards of ribbon bought by Marcella

so

12 1/4 - (2 1/2 + 3 2/3)

but first convert mixed number to an improper fractions

12 1/4 = 12*4+1/4 = 49/4

2 1/2 = 2*2+1/2 = 5/2

3 2/3 = 33+2/3 = 11/3

substitute in the expression above

49/4 - (5/2 + 11/3)

49/3 - (5*3+2*11/6)

3*49-37*2/12

73/12 yd

Convert to mixed number

73/12 yd = 72/12 + 1/12 = 6 1/12 yd

its a straight line parallel to the time axis

6.48/4 4 goes into 6.48 1.62 times
