If you're multiplying a whole number by a fraction, then multiply the whole number by the numerator, then divide that number by the denominator.

So in the case of 15 x (5/6), multiply the 15 by 5 (75) and then divide by 6 to get 75/6 (as an unsimplified answer).

In the case of 3 x (3/6), you again multiply the whole number by the numerator (3x3=9) and divide by the denominator (9/6) to get 9/6 or 3/2 when simplified.

Multiply both sdies by 10 to get rid of the fractions
20(4x+3)/5-60(x-2)/2=5
4(4x+3)-30(x-2)=5
distribute
16x+12-30x+60=5
add like terms
-14x+72=5
subtract 72 from both sdies
-14x=-67
multiplyh -1
14x=67
divide both sdies by 14
x=67/14

each person starts with $8.

<u>Step-by-step explanation:</u>

Here we have , Josh had $10 more than Carly, so he gave Carly half of his money. Then Carly had more money than josh, so she gave Josh $4. Then they both had $13. We need to find How much money did each person start . Let's find out:

Suppose Carly had $x , Josh had $10 more than Carly i.e. $(x+10), so he gave Carly half of his money i.e.

⇒ $\frac{x+10}{2}$ ,Now , Josh have $ $\frac{x+10}{2}$ & Carly have $x + \frac{x+10}{2}$ .
