Audrey's father gave her 20 tokens to use at Action
rjkz [21]

Answer:

5 tokens

Step-by-step explanation:

<u><em>She spent 1 out of every 4 tokens,</em></u> meaning there are a couple of sets of 4 that we don't know many they are yet that she kept taking from every set 1 token, so if we do,

(Her total tokens) 20 ÷ 4 = 5.
This means that there's 5 sets, then we take 1 from every set so 1 × 5 = 5, that's it

I don't know if that was quite clear tho you can imagine it in a more virtual than mathematical way if you like,

Now Imagine you have 20 tokens in your hand, and you divide them into 5 sets, each set is a set of 4, you keep 3 in your hand then put 1 on a table, then you do this 5 times you'll end up with 5 tokens on the table and 15 in your hand.

<em>You can try that yourself if you want it to be more clear.</em>

Take 20 small pieces of paper, sticky notes or coins whatever you like, then divide them into sets of 4, then lastly take only 1 from each set (and by the way you'll notice that dividing each set into a set of 4 will make you automatically end up with 5 sets) now count all the 1's you collected from each set
they should be 5.

MARK BRAINIEST The base of a triangle is 7 3/4 inches, and the height is 4 2/3 inches. What is the area of the triangle? A) 14 4
Keith_Richards [23]
Short Answer: B
Remark
The area of any triangle is 
A = 1/2 b * h
b = 7 3/4
h = 4  2/3

Step one
Convert all fractions to improper fractions.

7 3/4 = (28 + 3) / 4 = 31/ 4

4 2/3 = (12 + 2) / 3 = 14/3 Now multiply

Step Two
Multiply
Area = 1/2 * 31/4 * 14/3 Multiply the numerators together and then the denominators.
Area = (1 * 31 * 14) / (2 * 4 * 3) = 434 /24

Step 3
Convert this to a whole number + a fraction

Area = 18 + 0.08333333 You already have your answer. It is  B because only B gives an answer of 18. But you can get the rest of 

Let x = 0.083333333
100 x = 8.3333333333 
 <u>x =       0.0833333333 </u>  Subtract
99  x = 8.25 Divide by 3 on both sides.
33 x = 2.75  Divide by 11
3x  = 0.25  
x = 0.25/3 Multiply top and bottom by 4
x = 1 / 12

The answer is 18 1/12.
