Jan and Laura have a total of 3 same sized cookies they want to divide equally between the two of them. What fraction of the cookies should each girl receive?

Answers

Answer 1

Answer: There are three cookies and two girls. So divide the number of cookies over the number of people who want equal shares.
3/2 or 1 1/2
Each girl gets one and a half cookies.

Hope this helps :)

explain how you can use multiplication to find the quotient 3/5 divided by 3/15. then evaluate the expression

Answers

we know that

Dividing is the opposite of multiplying. Therefore, dividing by a fraction can be accomplished by multiplying by its reciprocal

$((a)/(b))/((c)/(d)) =(a)/(b)*(d)/(c)$

in this problem we have

$(a)/(b)=(3)/(5)\n \n(c)/(d)=(3)/(15)$

substitute in the formula above

$((3)/(5))/((3)/(15)) =(3)/(5)*(15)/(3)=3$

therefore

the answer is

$3$

$(3)/(5)$ ÷ $(3)/(15)$

⇒ $(3)/(5)$ × $(15)/(3) = (45)/(15) = 3$

The midpoint of the line segment from p1 to p2 is (-2,4). If p1=(-5,6), what is p2?

Answers

-5 to -2 is 3 units. Go 3 units farther and end up with 1.
6 to 4 is 2 units. Go 2 units farther and end up with 2.
Answer (1,2)

Answer:

P2 is (1, 2).

Step-by-step explanation:

The x values of the midpoint and P1 are - 2 and -5 . That is P1 is 3 to the left of the midpoint.

The y values of the midpoint and P1 are 4 and 6 . That is P1 is 2 up from the mid -2point.

So P2 has an x coordinate of 3 to the right of the midpoint and a y coordinate of 2 down from the mispoint.

So P2 is (-2+3), (4 -2)

= (1, 2).

What is 127km to the nearest 10km

Answers

127 rounded to the nearest 10 is 130 .

The ' 10s ' on each side of it are 120 and 130.
It's closer to 130.

You can tell that by looking at the units place.
If the units digit is less than 5, then it's closer to the lower ten.
If the units digit is 5 or more, then it's closer to the higher ten.
This units digit is 7, so it's closer to the higher ten . . . 130 .

127km = 130km since 7 in the tens digit is nearer to the 30 than 20 :)
