24. The fastest the runner ran was Wednesday.

Step-by-step explanation:

12⁄138 = 6⁄69 ≈ 0,0869565217

$\frac{3}{31,5} ≈ 0,0952380952$

___

4⁄37 = 0,108

6⁄72 = 1⁄12 = 0,083 ← smallest quantity, fastest time

4⁄38 = 2⁄19 ≈ 0,1052631578

$\frac{1}{5} = \frac{16}{80}$

Greatest Common Divisor [GCD]: 16

$\frac{2}{5} = \frac{4}{10}$

Greatest Common Divisor [GCD]: 2

$\frac{6}{25} = \frac{48}{200}$

Greatest Common Divisor [GCD]: 8

I need help it’s a quiz

Answer:

Question 6: 26 crowns plus 15 ribbons.

Question 7: 10 footballs plus 42 basketballs.

Step-by-step explanation:

Question 6 explanation: Since the expression is 22 crowns plus 13 ribbons plus 2 ribbons plus 4 crowns, you can think of the different items as variables in an equation. Picture crowns are the variable $x$ , and ribbons as the variable $y$ , this will help you solve the equation in an easier way that allows you to comprehend each step better. The equation will now be $22x+13y+2y+4x$ , in order to find how many $x$ (crowns) and $y$ (ribbons) you have, you need to combine like terms in the expression. In other words, add the terms with the variable $x$ together, and add the terms with the variable $y$ together. Simplified, the equation will be $26x+15y$ . Since the variables $x$ and $y$ were used to represent crowns and ribbons respectively, that means the correct answer is 26 crowns plus 15 ribbons.

Question 7 explanation: You can use the same method as you did in question 6, think of footballs and basketballs as the variables $x$ and $y$ respectively. The equation will be $16x+38y-6x+4y$ = $10x+42y$ . Since the variable $x$ was used to represent footballs and the variable $y$ was used to represent basketballs, that means the correct answer would be 10 footballs plus 42 basketballs.
