Answer :

Let's solve each part of the question step-by-step:

  1. Cake Sale:

    • If each class needs to sell 65 slices of cake and there are 18 classes in total, we multiply the number of slices each class needs to sell by the number of classes.
    • [tex]65 \times 18 = 1170[/tex]
    • Therefore, the total number of slices the classes need to sell is 1170.

  2. Nina's Running:

    • Nina runs 24 km each week for 12 weeks.
    • To find the total distance she will run, multiply the distance per week by the number of weeks.
    • [tex]24 \times 12 = 288[/tex]
    • Nina will run a total of 288 km.

  3. Chairs in the Hall:

    • There are 22 rows of chairs with 28 chairs in each row.
    • To find the total number of chairs, multiply the number of rows by the number of chairs per row.
    • [tex]22 \times 28 = 616[/tex]
    • There are a total of 616 chairs in the hall.

  4. Product of 315 and 15:

    • To find the product of 315 and 15, multiply the two numbers together.
    • [tex]315 \times 15 = 4725[/tex]
    • The product is 4725.

  5. Megan's Pancakes:

    • If Megan bakes 252 pancakes each day, and you want to know how many she will bake in 21 days, multiply the number of pancakes per day by the number of days.
    • [tex]252 \times 21 = 5292[/tex]
    • Megan will bake a total of 5292 pancakes in 21 days.
