How do you figure out this math question?

A hamburger shop jus opened and offered 2 different kinds of buns and 5 different toppings. How many different burgers can you make using 1 type of bun and 1 topping?



- My daughter just needs to know what to do with it



And another one :



Jasmin is planting a garden in her backyard. The garden is fourteen ft long. She wants to plant one row of beans the entire length of her garden. She wants to plant a seed at each end of the row every 2 feet along it. How many seeds will she need?How do you figure out this math question?
you multiply:

2x5=10



so the answer is 10 different type of burger combinations

or you can do a factor tree



key:

B= buns



Topping1 Topping2 Topping3 Topping4 Topping5

/ \ / \ / \ / \ / \

B1 B2 B1 B2 B1 B2 B1 B2 B1 B2



Therefore

Topping 1 with Bun 1

Topping 1 with Bun 2



Topping 2 with Bun 1

Topping 2 with Bun 2



Topping 3 with Bun 1

Topping 3 with Bun 2



Topping 4 with Bun 1

Topping 4 with Bun 2



Topping 5 with Bun 1

Topping 5 with Bun 2How do you figure out this math question?
You've got 2 buns and 5 toppings.

If you only had one bun and 5 toppings, you could make 5 different burgers, right?



But you've got 2 buns, so you make double that(by changing the bun)



So you've got 2*5 = 10





Same kind of idea for the second one



14 divided by 2 = 7How do you figure out this math question?
With the first bun, and 5 different toppings, = 5 varieties

With the 2nd bun, and 5 different toppings, = 5 varieties

Total varieties=10

Note 2 buns X 5 varieties = 10



She needs 8 seeds.

She needs a seed every 2 feet, so 2 X 7=14

AND, one to start the row

Total= 8
Did she get that from the Glencoe Mathematics Grade 6 Mathematics Review book?
