Answer:
2/1
Step-by-step explanation:
Each Student would get 3/16 of the pizza. This is because when you have a fraction, it's the same as saying dividing. So 3/4 is equal to 3÷4. Once you have 3÷4= 0.75. then you can divide that by 4, getting 0.1875. Although this is still an exact calculation, most people would automatically understand better in the fraction form of 3/16, so it is better to switch it back. This can be done either on your own or with a calculator, most scientific calculators have the ability anyways so it shouldn't be a big deal. In the end, if the pizza has 16 slices, each student gets 3, if it has 8, then each student gets 1 1/2.

U do the butterfly or X multiplication method.
4x * x = 4x

4x/100 = 25
<h2>Answer:</h2>
Number of biology textbooks sold: 257 textbooks
Number of psychology textbooks sold: 181 textbooks
<h2>Explanations:</h2>
Let the total number of biology textbook sold be "a"
Let the total number of psychology textbook sold be "b"
If a textbook store sold a combined total of 438 biology and psychology textbooks in a week, then:
a + b = 438 ................... 1
If the number of psychology textbooks sold was 76 less than the number of biology textbooks sold, then;
b = a - 76 ...................... 2
Substitute equation 2 into 1
a + (a-76) = 438
a + a - 76 = 438
2a = 438 + 76
2a = 514
a = 514/2
a = 257 biology textbooks
From equation 2;
b = a - 76
b = 257 - 76
b = 181 psychology textbooks
Number of biology textbooks sold: 257 textbooks
Number of psychology textbooks sold: 181 textbooks
