1. |b/5|=1 take the equation out of the absolute value
b/5=1
*5 *5 multiply both sides by 5
_____
b=5
2. 2-5|5m-5|=-73 get rid of what's outside the absolute value first
-2 -2 subtract 2 from both sides
____________
-5|5m-5|=-75
÷-5 ÷-5 divide both sides by -5
__________
|5m-5|=15 take the equation out of the absolute value
5m-5=15
+5 +5 add 5 to both sides
_______
5m=20
÷5 ÷5 divide both sides by 5
_____
m=4
3. |7p+4|/8=3
*8 *8 multiply by 8
__________

______
p=20/7
4. 5-8|-2n|=-80
+5 +5 add 5
__________
-8|-2n|=-80
÷-8 ÷-8 divide by -8

The numerator (top number of the fraction) is adding up by odd numbers in order.
From 1/40 to 4/40 you add 3, from 4/40 to 9/40 you add 5, from 9/40 to 16/40 you add 7, and from 16/40 to 25/40 you add 9.
The next number to add would logically be 11. So from 25/40 you would go to 36/40.
36/40 is your next fraction.
