The numbers are both equal because, 6.80 is six and eight hundredths, and 6.8 is six and eight tenths. When writing decimals any zero added to the end of the number has no value, 8/10 as a fraction is equal to 80/100 if simplified, so Nicky and Marta wrote equal numbers. :)

Answer:
x=2/3
Step-by-step explanation:
(2x+1)/2 = 2 1/3/4
Multiply 4 on both sides:
2x+1=2 1/3
Rewrite:
2x+1=7/3
Subtract 1 on both sides:
2x=4/3
Divide 2 on both sides:
x=2/3
Thus x=2/3
