Answer:
26 5/12
Step-by-step explanation:
n − 2/3 = 25 3/4 Add 2/3 to both sides
n - 2/3 + 2/3 = 25 3/4 + 2/3 Combine
n = 25 3/4 + 2/3
Work with the fractions
3/4 + 2/3 The lowest common denominator is 12
(3*3)/(3*4) = 9 / 12
(2*4)/(3*4) = 8/ 12
9/12 + 8/12 = 17/12 = 1 5/12
Now you need to add 1 to 25
1 + 25 = 26
And add the fraction 5/12
The answer is 26 5/12

Subtraction is a mathematical operation that reflects the removal of things from a collection. The number of bags that zips on them is 78.
<h3>What is subtraction?</h3>
Subtraction is a mathematical operation that reflects the removal of things from a collection. The negative symbol represents subtraction.
Given the number of bags that the company makes is 140. 39 of the bags have buttons but no zips. 21 of the bags have zips but no buttons. 23 of the bags have neither zips nor buttons.
Bags that have both zip and button
= Total number of bags - Number of bags with zips but no buttons - Number of bags with buttons but no zips - Number of bags with nor zips nor the buttons
= 140 - 21 - 39 - 23
= 57
Now, the number of bags that has zips will be the bags that only have zips and the number of bags that has zips and buttons. Therefore, the number of bags with zips is,
n = Bags that have both zip and button + Number of bags with zips but no buttons
= 37 + 21
= 78
Hence, the number of bags that zips on them is 78.
