Answer:
x=3
Explanation:
5/10 is equal to 1/2, and 1/2 of 100 is 50. Lets make that into a fraction.
5/10=1/2=50/100
Lets multiply everything by 100.
50/100(100)+x/100(100)=53/100(100)
50+x=53
Subtract 53 from both sides
x=3
Check your work
5/10+3/100=53/100
50/100+3/100=53/100
53/100=53/100
:)
Hope this helps!
