your answer.
Help please

Respuesta :

Answer:

Magdalena has 9 puzzles left to complete.

Step-by-step explanation:

1. Convert the percentage of puzzles you finished to a decimal by dividing by 100%.    55% ÷ 100% = 0.55

2. Multiply the total number of puzzles by 0.55 to get how many puzzles she has already completed.    20 x 0.55 = 11

3. Subtract the amount of puzzles Magdalena has already completed from the total amount of puzzles. 20 - 11 = 9

4. Therefore, Magdalena has 9 puzzles left to complete
