help me me me i need help to get 100

Answer:
45 pounds
Explanation:
Each cupcake is 0.45 pounds
They are asking for the weight of a hundred
So Multiply
0.45*100
So since its multiplying by base 10s
A easier way is to count the zeros and move the decimal place to the right (positive) to the amount of 0s
So 100 has 2 0s
Now 0.45
Move 2 decimal paces to the right
45
