Answer 1

x = 3

Explanation:

Do the inverse of addition and that will be subtraction.

53/100 - 5/10 = 3/100

Add 3/100 and 5/10 to check if you have the correct answer, (it is)

Answer 2

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!
