Answer:
To find out how many meters of cloth Nena had left, we need to subtract the amount of cloth she used for her project from the total amount she bought.
Nena bought 2 1/2 meters of cloth, which can be written as 2.5 meters.
She used 3/4 of a meter for her project.
To find the amount of cloth she had left, we subtract 3/4 from 2.5:
2.5 - 3/4
To subtract fractions, we need a common denominator. The common denominator of 4 and 1 is 4.
Converting 2.5 to a fraction with a denominator of 4:
2.5 = 2 2/2 = 2 4/4 = 10/4
Now we can subtract:
10/4 - 3/4 = (10 - 3)/4 = 7/4
So, Nena had 7/4 meters of cloth left.
