A cookie factory uses 1 1/3 barrels of oatmeal in each batch of cookies. The factory used 2 2/3 barrels of oatmeal yesterday. How many batches of cookies did the factory make?

2 batches

Step-by-step explanation:

A cookie factory uses 1 1/3 barrels of oatmeal in each batch of cookies

The factory used 2 2/3 barrels of oatmeal yesterday

Therefore the batches of cookies that were made yesterday can be calculated as follows

1 batch= 1 1/3 barrels

x = 2 2/3 barrels

Cross multiply

4/3 x = 8/3

x= 8/3 ÷ 4/3

x = 8/3 × 3/4

x= 2

Hence 2 batches will be produced

A ratio can be expressed as a:b or a/b.

We know that Pam spends 45 minutes going to work and 60 minutes when go to home from work. And we are told to write the ratio of minutes spent on driving from home to work to minutes spent on driving to home from work.

Going to work => 45
Going back to home => 60

Easy. 45:60 or 45/60. Now like a fraction, we must simplify. Find two numbers that will evenly divide into both top and bottom.

15 should do.

45/60 / 15/15 = 3/4

So, the ratio is 3:4 or if you want in a fraction form, 3/4.
