Rebecca needs 10 ½ yards of fabric to make a quilt. She has one piece of fabric that is 2 ½ yards and another piece of fabric th

muminat

Answer:

3 $\frac{3}{4}$ yards of fabric

Step-by-step explanation:

In order to solve this problem, we should first make all of the fractions have common denominators. To do so we can turn the 1/2s into 2/4 which both equal 0.5 or 50%. Now we simply need to add together the pieces of quilt that she has and subtract that value from the total that she needs in order to calculate the amount of quilt that she is missing.

10 $\frac{2}{4}$ - (2 $\frac{2}{4}$ + 4 $\frac{1}{4}$ ) = x

10 $\frac{2}{4}$ - 6 $\frac{3}{4}$ = x

3 $\frac{3}{4}$ = x

Finally, we can see that Rebecca needs a total of 3 $\frac{3}{4}$ yards of fabric to finish her quilt.

Arlecino [84]

Answer:

First deposit - Same amount

Second deposit - Sylvia

Third deposit - Sylvia

Step-by-step explanation:

Leroi put $200 in their account. They will add $40 every week.

Deposit 1: $240

Deposit 2: $280

Deposit 3: $320

Sylvia put $200 in their account. They will add 20% of the amount in the account each week.

Deposit 1: $240 (20% of $200 is $40)

Deposit 2: $288 (20% of $240 is $48)

Deposit 3: $345.60 (20% of $288 is $57.60)

So, Sylvia and Leroi have the same amount of money in their accounts after the first deposit. After the second and third deposit, Sylvia has more money.
