Explanation:
Im not sure about the first two about fraction bars, a fraction bar looks like this 1/10 or 4/9, maybe the question is asking you to make a fraction of each side so that they both equal the same thing using common denominators.
In that case #2 would be 21/3= 21/7
still not sure about #1
X+32=40
subtract 32 on each side
x+32-32=40-32
x=8
At a restaurant, Mike and his three friends decided to divide the bill evenly. If the total bill was $51.24, how much did each person pay?
Write and solve an equation for the above situation. Use "b" as the variable
4b=51.24
divide each side by 4
4b/4= 51.24/4
b=12.81
Each friend spent $12.81 on the bill.
How many packages of diapers can you buy with $40 if one package costs $8?
Write and solve an equation for the above situation. Use "p" as the variable

divide each side by 8
8p/8=40/8
p=5
You can buy 5 packages of diapers with $40
