Answer:
a) To work out 10% of the original price of the television, we can multiply the original price by 0.1:
10% of £300 = 0.1 × £300 = £30
Therefore, 10% of the original price of the television is £30.
b) To work out the sale price of the television, we can subtract 10% of the original price from the original price:
Sale price = Original price - 10% of original price
Sale price = £300 - £30
Sale price = £270
Therefore, the sale price of the television is £270.
