Answer:

1. SCR (or PPW). 43 more flavors

2. GLT. 41,976 notebooks

Step-by-step explanation:

1. Conceptual key: SCR

Lizzy is starting with 37 flavors. She wants a result of 80 flavors, so the change can be computed from ...

37 + x = 80

x = 80 -37 = 43

Lizzy needs to create 43 more flavors.

Additional comment

This might also be considered to be using the PPW pattern, as both the number she has and the number she creates make up the whole number. The SCR key may better apply to cases where a "rate of change" is involved. There is no rate of change in this problem.

_____

2. Conceptual key: GLT

There are 212 groups of 198 notebooks, so the total is the number of groups times the number in each group.

(212 boxes)(198 notebooks/box) = 41,976 notebooks

Answer: Write the expression as:

" 70 $\frac{32}{100}$ +
2 $\frac{1}{10}$ * 2 $\frac{7}{10$ − 18a " ;
______________________________________________________
or; write as:
______________________________________________________
" 70.32 + (2.1) * (2.7) − 18a " ;
______________________________________________________

To simplify:
______________________________________________________

Using "PEDMAS" (the "order of operations") ;

the "multiplication" comes first;

So: → "(2.1) * (2.7) = 5.67 " .

And rewrite:
______________________________________________________
" 70.32 + 5.67 − 18a " .

Now: " 70.32 + 5.67 = 75.99 " ;

So, we can the final simplified expression as:
______________________________________________________
" 75.99 − 18a " ;

or; write as: " 75 $\frac{99}{100}$ − 18a " .

Please answer the following questions: 1. 1/2*8= 2. 1/4*4= 3. 1/3*6=

yan [13]

Hey there!

When we multiply fractions and whole numbers, we simply take that whole number and put it over them, and just multiply across. That gives us:

$\frac{1}{2}x*8 = \frac{8}{2} = 4$

Notice how it's four, because when we have a fraction, we divide. 8 divided by 2 equals four. Next:

$\frac{1}{4} *4 = \frac{4}{4} = 1$

4/4 is equal to 1 because 4 divided by 4 is one. 4 goes into 4 once. Next, we have:

$\frac{1}{3}*6 = \frac{6}{3} = 2$

That's because 6/3 = 2.

Hope this helps!
