Zina [86]

Answer:

2 dimes, 1 nickel and 3 quarters.

Step-by-step explanation:

The price of 2 postcards is $1. Any combination of coins that adds to $1 will work here. Remember, a penny is worth 0.01, a nickel is worth 0.05, a dime is worth 0.10, and a quarter is worth 0.25.

Adding 2 dimes, 1 nickel, and 3 quarters would be 2(0.10)+1(0.05)+3(0.25)=1.

defon

Answer:

Step-by-step explanation:

Though it is not obvious, the c belongs in the numberator, not the denominator.

So C and D are both wrong.

9: 3 * 3

3: 3

4:2 * 2

Lowest common denominator = 2 * 2 * 3 * 3

Lowest common denominator = 36
