it would depend how much you actually used, but you would take the amount you used and divide it by the total amount of yarn. so if the yarn was 4m long and you used 2m then it would be 2/4 which is 0.5 which is also 50%, so half the yarn was used.
Answer:
To make a high estimate for the sum of two fractions, find the commnon denominator and add them.
Step-by-step explanation:
To make a high estimate for the sum of two fractions in a word problem, rhe following steps are required.
Let the two fractions be represented as and
To perfrom the operation +
Step 1 : Check if the denominators of the fraction are same. If so then, then add the numerators directly by keeping the same denominator.
Step 2: If the denominators are different, then find the common denominator between the fractions and multiply them accordingly. Then perform the addition operation.
Y because if you add them you will get 10x =-10
The y will be eliminated because you have positive 3 -4
