Answer:
Answer: one fourth
Fourth is a word that used to describe a number value of 1/4. To answer this question, you need to change the number you got (3/12) into x/4 form. To convert 12 into 4, then you need to divide the numerator and denominator with 3. The equation would be (3/3)/(12/3)= 1/4.
To determine how much fourth the number has, you need to divide the result with 1/4. The calculation would be: (1/4)/ (1/4)= one fourth
hope its help
thank you
good day
You sure seem to be asking a lot of questions lately. I'd like to see that you've been trying with these problems at least because if you can't get that first one it's almost like you missed the whole lesson.
1. 20 = 4b + 7 + 5
Add the 7 and 5.
20 = 4b + 12
Subtract 12 from each side.
8 = 4b
Divide each side by 4.
2 = b
2. 7 = 6k - 7k
6k - 7k = -1k. (the k acts as a sort of unit)
7 = -1k
Divide each side by -1.
-7 = k
3. 3.23 - 2m = 3 - 2(5m - 2)
Distribute the ×-2 to each term inside the parentheses.
3.23 - 2m = 3 - 10m + 4
Add the 3 and 4.
3.23 - 2m = 7 - 10m
Add 10m to each side.
3.23 + 8m = 7
Subtract 3.23 from each side.
8m = 3.77
Divide by 8.
m = 0.47125
4. -88/45=1/3r+2/5r
To get rid of the fractions, let's multiply everything by 45.
-88 = 15 + 18r
Subtract 15 from each side.
-103 = 18r
Divide by 18.
-103/18 = r
As a mixed number, r = -5 and 13/18
As a decimal, r = -5.7222...
Answer:
This fraction is in the simplest form already.

(4,300)
So in 4 hours, you make 300 cookies
Divide cookies by hour
300/4 = 75
Solution: 75 cookies per hour
NO is 2 times LM
2(x+1) = 4x
2x + 2 = 4x
2 = 2x
1 = x
Plug that in for 4x
4(1)
