Question

a principal orders 8 sub sandwiches for a teachers meeting. she cuts the subs into thirds and puts the mimi sub onto a tray how many mini subs were on the tray

Answer 1

1 sub is divided into thirds, so there are now 3 parts to each sub. Multiply the three parts per sub by the total number of subs purchased.

Find # Parts Per Sub
= 1 sub ÷ 1/3
multiply by the reciprocal of 1/3
= 1 * 3/1
= 3 parts per sub

Find Total Parts
= 8 subs * 3 parts per sub
= 24 mini subs

ANSWER: 24 mini subs

Hope this helps! :)

Answer 2

There are 24 mini subs sandwiches on the tray.

Further Explanation

Given:

• There 8 sub sandwiches
• Each sandwiches cuts into third

Question

How many mini subs were on the tray?

Each sandwiches cut into 1/3 so:

$\boxed {1 : \frac{1}{3} = 1 \times3 = 3 }$

so 1 sandwich cuts into 3 mini subs

if there are 8 sandwiches, so there will be :

$\boxed {8 \times3 = 24}$

There will be 24 mini subs on the tray.

Other way to solve this problem is by doing a proportions:

Let's say the total mini sub is x, so the equation will be:

1 sandwiches =  8 sandwiches

3 mini subs           x mini subs

x mini subs = 8 sandwiches x 3 mini subs = 24 mini subs

                                    1 sandwich  

we can cancel out the sandwich unit.

So, 8 sandwiches  can be cut into 24 mini subs.
