Just divide 2 4/5 by 2:  

Convert 2 4/5 into the improper fraction 14/5, and then divide this result by 2:

7/5, or 1 2/5, tablespoons of medication, twice per day (total 2 4/5 tablespoons)

A jar is full of 100 coins. All of the coins are either nickels or dimes.
Elza [17]

Answer:

73 nickels, 27 dimes

Step-by-step explanation:

x+y=100

5x+10y=635

x=100-y

5(100-y)+10y=635

500-5y+10y=635

500+5y=635

5y=135

y=27

5x+10(27)=635

5x+270=635

5x=365

73

73+27=100
