Answer:

  • Brian over Colin: £39.20
  • Colin over Brian: -£39.20

Step-by-step explanation:

The total of ratio units is 2+1+5 = 8. Brian gets 5 and Colin gets 1, so Brian gets (5-1) = 4 ratio units over Colin. Of the total tips, that is 4 of 8 ratio units or 4/8 = 1/2 of the tips:

  Brian over Colin = (1/2)(£78.40) = £39.20

The amount Colin gets over Brian is the opposite of this: -£39.20.

What is the solution to the equation k- 4 3/4 = 8 1/4
zhuklara [117]

Answer:

<h2>k = 13</h2>

Step-by-step explanation:

<h3>k - 4 \frac{3}{4}  = 8 \frac{1}{4}</h3>

To solve first change the mixed number to an improper fraction

That's

<h3>4 \frac{3}{4}  =  \frac{19}{4}</h3><h3>8 \frac{1}{4}  =  \frac{33}{4}</h3>

So we now have

<h3>k -  \frac{19}{4}  =  \frac{33}{4}</h3>

Move the fraction to the right side of the equation

That's

<h3>k =  \frac{33}{4}  +  \frac{19}{4}</h3>

Since they have the same denominator we can add them directly

We have

<h3>\frac{33}{4}  +  \frac{19}{4}  =  \frac{52}{4}  = 13 </h3>

we have the final answer as

<h3>k = 13</h3>

Hope this helps you
