Let's solve each part of the question step by step.
To find out how many stickers Nadia has after three days, we need to add up the stickers she collected each day.
Monday: 1,245 stickers
Tuesday: 2,367 stickers
Wednesday: 1,789 stickers
To get the total number of stickers, we add these numbers together:
1 , 245 + 2 , 367 + 1 , 789 = 5 , 401
So, Nadia has a total of 5,401 stickers after three days.
For Aleena's collection, we need to find out how many stickers she has left after giving some away.
Total stickers Aleena has: 8,432
Stickers given away: 3,758
Subtract the stickers given away from the total:
8 , 432 − 3 , 758 = 4 , 674
Aleena has 4,674 stickers left.
Sarah is planning her garden by planting flowers. She wants to have 8 rows, with each row containing 15 flowers. To find out how many flowers in total, we multiply:
Number of rows: 8
Flowers per row: 15
Calculate the total number of flowers by multiplying the two numbers:
8 × 15 = 120
Therefore, Sarah will plant about 120 flowers in total.
Each part of this problem involves basic arithmetic operations like addition, subtraction, and multiplication, which are fundamental in middle school mathematics. I hope this explanation helps!
