Yes half of 8 is 4 equaling 4/8. Since she knitted 5/8, then she knitted more than 1/2. Hope this helps:)

Answer:

Fraction of Scarf Knitted by Bess

=\frac{5}{8}

Remaining fraction of Scarf which is to be Knitted

1-\frac{5}{8}=\frac{3}{8}

equivalent fraction in eighths for 1/2

=\frac{1}{2}\times \frac{4}{4}\\\\=\frac{4}{8}

\frac{5}{8}>\frac{4}{8}=\frac{1}{2}

Yes, Bess has knitted more than =\frac{1}{2} of the scarf.

Answer:

1. 15, 16, 17

2. 21, 23, 25

3. 44, 46, 48

4. -4, -3, -2

Step-by-step explanation:

1)

Step 1. Writing an equation

Let's set x as the second number in the equation.

This means that the first number is x-1, and the third number is x+1.

We know that the sum of the three numbers is 48, so:

(x-1)+x+(x+1)=48

Step 2. Solving the equation

x-1+x+x+1=48

x+x+x-1+1=48

3x=48

x=16

<em>So the answer is 15, 16, 17</em>

2)

Again, let's set x as the middle number.

Odd numbers are 2 numbers apart, so the first number is x-2, and the third is x+2.

This means that the equation must be:

(x-2)+x+(x+2)=69

x+x+x=69

3x=69

x=23

<em>The numbers are 21, 23, and 25</em>

3)

x will be the middle number

Even numbers are 2 numbers apart, so the first number is x-2, and the third is x+2.

This means that:

x-2+x+x+2=138

x+x+x=138

3x=138

x=46

<em>The numbers are 44, 46, and 48.</em>

4)

x will be the middle number.

x-1=first number, x+1=third number

x-1+x+x+1=-9

3x=-9

x=-3

<em>The numbers are -4, -3, and -2.</em>

What is the greatest number of 19 cent stickers that can be purchased with a $20 bill, assuming there is no sales tax?
user100 [1]

Answer:

105

Step-by-step explanation:

First, you are going to convert dollars to cents. Since there are 100 cents in a dollar, multiple $20 by 100. Now you should have 2,000 cents. Now all you have to do is divide by 19, the cost of the stamps, and you should get 105.26. Because you can't by part of a stamp your answer would be 105.
