a) -4.11%
b) 2.74%
c) 0%
d) -1.36%

Explanation:

"Percent error" is the difference between the "actual" value and the measured value.
$% error = \frac{measured - actual}{actual} \times 100$ $%"error" = ("measured" - "actual")/"actual" xx 100$

7.0: $% error = \frac{7.0 - 7.3}{7.3} \times 100 = - 4.11 %$ $%"error" = (7.0 - 7.3)/7.3 xx 100 = -4.11%$

7.5: $% error = \frac{7.5 - 7.3}{7.3} \times 100 = 2.74 %$ $%"error" = (7.5 - 7.3)/7.3 xx 100 = 2.74%$

7.3: $% error = \frac{7.3 - 7.3}{7.3} \times 100 = 0 %$ $%"error" = (7.3 - 7.3)/7.3 xx 100 = 0%$

7.2: $% error = \frac{7.2 - 7.3}{7.3} \times 100 = - 1.36 %$ $%"error" = (7.2 - 7.3)/7.3 xx 100 = -1.36%$
