Answers

Answer:

4

Step-by-step explanation:

This is correct because to divided you have to keep, change, flip. First you want to change into in improper fraction of 16/3 and 4/3. The you want to keep your first number of 16/3 and change you sign to multiplication then flip you number of 4/3 to 3/4 and this is your formula.

16/3 x3/4= 48/12 which simplified= 4

Solve y/3 = -6 using inverse operation. Show work.

Answers

y= -18
3/1*y/3=-6*3/1
inverse means opposite so you multiply by the opposite of y/3 which is 3/1 to just get y and what you do to one side, you have to do to the other which leads to your answer y= -18
-18/3=-6

-6 mulitplied by 3 equals -18

Julie started with 20 pieces of gum and gave away x pieces. Conrad started with 35 pieces of gum and gave away twice as many pieces as Julie did.

How many pieces of gum did Julie give away if they had the same number of pieces of gum left?

Answers

Answer:

15

Step-by-step explanation:

See picture

Julie gave away 15 pieces.

I found my answer by making an equation. For Julies half, we do 20-x because we don't know how many pieces she gave away but we do know how many pieces she started with. For Conrads half, we do 35-2x because we know he started out with 35 pieces and gave away two times how much Julie gave away so 2x. Then because we want them to have the same amount of gum left we set their two halves as equal to eachother.

So our equation is 20-x=35-2x. Then we solve:

20-x=35-2x (then we subtract 20 from both sides to move it right)

-x=15-2x (then we add 2x to both sides to move it left)

x=15 (and here is out answer)

How many times can each of the pieces of the fraction bars be divided to model Three-fourths minus one-third? Each piece of each bar can be divided into 2 pieces. Each piece of each bar can be divided into 12 pieces. Each piece of the Three-fourths bar can be divided into 3 pieces, and each piece of the One-third bar can be divided into 4 pieces. Each piece of the bar can be divided into 4 pieces, and each piece of the bar can be divided into 3 pieces.

Answers

Answer:

Each piece of the Three-fourths bar can be divided into 3 pieces, and each piece of the One-third bar can be divided into 4 pieces.

Step-by-step explanation:

If each piece of the Three-fourths bar is divided into 3 pieces,then you will get total pieces of 12.

In the same way, when each piece of the One-third bar is divided into 4 pieces, total pieces is 12.

After this we can subtract

Answer:

C.  Each piece of the Three-fourths bar can be divided into 3 pieces, and each piece of the One-third bar can be divided into 4 pieces

Can someone explain how to solve 3/4 + 7/8 + 1/2 as a mixed number in simplest form

Answers

Answer: What you hav to do is to simplify. That’s obvious so let me explain better.

Step-by-step explanation:

3/4 in its simplist form would be 1 1/4 because how many times does three go into four? Only once so it’s 1 and 1/4. Then you repeat this process. 7/8, 1 1/8

btw I hope I, right cuz I’m not the best at math..... sorry if I got it wrong ;-;

it’s 2 1/8 bc 3/4 is equal to 6/8, 7/8 stays, and 1/2 is equal to 4/8. You just add all of those for a total of 17/8. 8•2=16 with one leftover. 2 1/8.
