Answer
To calculate £4.25 + £5.18, convert the amounts into pence for easier computation:
£4.25 = 425 pence
£5.18 = 518 pence
Adding them together:
425 + 518 = 943 pence
Now convert back to pounds:
£943 ÷ 100 = £9.43
Therefore, £4.25 + £5.18 = £9.43.

Answer
For the division -6 ÷ -9:
Dividing two negative numbers gives a positive result:
-6 ÷ -9 = rac{6}{9} = rac{2}{3}
Therefore, -6 ÷ -9 = ** rac{2}{3}**.

Answer
To compare 4.5 and 4.34:
Since 4.5 is greater than 4.34, the appropriate symbol is '>'.
Thus, the statement is 4.5 > 4.34.

Answer
To compare \( rac{3}{4}\) and 0.8:
\( rac{3}{4} = 0.75\), so \( rac{3}{4} < 0.8\).
Therefore, the correct statement is (\frac{3}{4} < 0.8).
