If frank has 24 pennies 62 nickles 55 dimes 16 quarters and 19 fifty cent pieces how much money does he have
Nitella [24]

Answer:

Frank has $22.34.

Step-by-step explanation:

24 pennies - 0.01 x 24 = 0.24

62 nickels - 0.05 x 62 = 3.10

55 dimes - 0.10 x 55 = 5.50

16 quarters - 0.25 x 16 = 4.00

19 half dollar (50cent) - 0.50 x 19 = 9.50

0.24 + 3.10 + 5.50 + 4.00 + 9.50 = 22.34

Also, as we go down, we divide each of either sides by 2 to get the next term

in line

So we fill in the ratio as follows;

32:8

16: 4

8:2
