Answer 1
Answer:

Answer

Find out the  how many cookies will each student get.

To prove

As given

mr.chan made 252 cookies for the annual fifth grade class bake sale .

they sold (3)/(4) of them

Than

Number\ of\ cookies\ left = (3* 252)/(4)

                                                = 189

Number of cookies left after sold = 252 - 189

                                                       = 63

(3)/(9) of the remaining cookies were given to P.T.A members .

Than

Number\ of\ cookies\ left\ when\ given\ to\ P.T.A\ members = (3* 63)/(9)

                                                                                               = 21

Number of cookies left after giving to P.T.A members = 63 - 21

                                                                                          = 42

As given

mr.chan allowed the 12 student helper to divide the cookies that are left equally.

Each\ student\ get\ cookies =(42)/(12)

                                                     = 3.5

Therefore the 3.5 cookies each student gets.
Answer 2
Answer:

3¹/₂ or 3.5 cookies

Further explanation

Given:

  • Mr. Chan made 252 cookies for the Annual Fifth Grade Class bake sale.
  • They sold (3)/(4) of them and (3)/(9) of the remaining cookies were given to P.T.A members.
  • Mr. Chan allowed the 12 student helper to divide the cookies that are left equally.

Question:

How many cookies will each student get?

The Process:

Step-1

Let \ us \ prepare \boxed{252 / 4 = 63}

Then, let us create a suitable diagram as follows:  

\boxed{63}\boxed{63}\boxed{63}\boxed{63} = 252 \ cookies}  

So, 1 unit of diagram is equal to 63 cookies.

  • Mr. Chan sold (3)/(4) of them, that is \boxed{ \ 3 \ units * 63 \ cookies = 189 \ cookies \ sold \ }
  • The remaining cookies are \boxed{ \ 252 - 189 = 63 \ cookies \ }, or 1 unit left of the diagram above.

Step-2

Let \ us \ prepare \boxed{63 / 9 = 7}

Then, let us create a suitable diagram as follows:  

\boxed{7}\boxed{7}\boxed{7}\boxed{7}\boxed{7}\boxed{7}\boxed{7}\boxed{7}\boxed{7} = 63 \ cookies}  

So, 1 unit of diagram is equal to 7 cookies.

  • Next, (3)/(9) of the remaining cookies were given to P.T.A. members, that is \boxed{ \ 3 \ units * 7 \ cookies = 21 \ cookies \ }.
  • The last number of cookies remaining was \boxed{ \ 6 \ units * 7 \ cookies = 42 \ cookies \ } or \boxed{ \ 63 - 21 = 42 \ cookies \ }.

Step-3

Mr. Chan allowed the 12 student helper to divide the cookies that are left equally.

Let us calculate how many cookies will each student get.

\boxed{ \ 42 \ cookies / 12 \ students \ }

\boxed{ \ = (42)/(12) \ }

The numerator and denominator are equally divided by 6.

\boxed{ \ = (42 / 6)/(12 / 6) \ }

\boxed{ \ = (7)/(2) \ }

\boxed{ \ = (6)/(2) + (1)/(2) \ }

\boxed{\boxed{ \ = 3(1)/(2) \ }}

Thus, each student will get3(1)/(2)cookies.

Write an expression that can be used to multiply 6 x 198 mentally? please answer thanks!

Answers

-6 x 2 + 6 x 200. Since you want to find out 6 multiplied by 198 the easiest way (for me) would be to round it and then substract 12 since 200-198 is equal to 2 and 6 x 2 is equal to 12
Assuming you meant 6 x 198... Do a mental sum for 6 x 200 (1200) then subtract 6

Are natural numbers always/sometimes/never rational numbers

Answers

Natural numbers are sometimes rational numbers

Final answer:

Natural numbers are always rational numbers since they can be expressed as fractions with a denominator of 1.

Explanation:

Natural numbers are always rational numbers. A rational number is any number that can be expressed as a fraction, where the numerator and denominator are both integers. Since natural numbers are a subset of integers (positive whole numbers), they can be expressed as fractions with a denominator of 1. For example, the natural number 5 can be written as the fraction 5/1, which is a rational number.
