Answer:
The number of textbooks of each type were sold is <u>134 math </u>and <u>268 psychology </u>books.
Step-by-step explanation:
Given:
Total number of math and psychology textbooks sold in a week is 402.
Now, let the number of math textbooks sold be
.
And, the number of psychology textbooks be
.
According to question:


Dividing both sides by 3 we get:

So, total number of math textbooks were 134 .
And, total number of psychology textbooks were 
.
Therefore, the number of textbooks of each type were sold is 134 math and 268 psychology books.
So basically a decimal is moved based on how many zeros are in the dividing number
Ex. 51,000/100
because there are 2 zeros in the number one hundred, the decimal in 51,000 gets moved 2 places to the left
So it goes from 51,000 to 510
Ex. 16 * 1000
There are three zeros in the number 1000. This means three zeros will be added onto the number 16
So the answer would be 16,000
Hope this helps!
