Understanding the Problem

In this problem, we are given the original price of a cardigan as £49 and are asked to find the reduced price after a discount of 3/7. To solve this problem, we need to understand the concept of discounts and how to calculate the reduced price.

What is a Discount?

A discount is a reduction in the price of an item. It is usually expressed as a percentage or a fraction of the original price. In this case, the discount is 3/7, which means that 3 parts out of 7 parts of the original price will be deducted.

Calculating the Reduced Price

To calculate the reduced price, we need to multiply the original price by the fraction of the discount. In this case, the fraction of the discount is 3/7, and the original price is £49.

Reduced Price = Original Price x (1 - Discount Fraction)

In this case, the discount fraction is 3/7, so we can write:

Reduced Price = £49 x (1 - 3/7)

To simplify the calculation, we can first find the value of 1 - 3/7.

1 - 3/7 = 4/7

Now, we can multiply the original price by 4/7 to find the reduced price.

Reduced Price = £49 x 4/7

To calculate the reduced price, we can multiply £49 by 4 and then divide the result by 7.

£49 x 4 = £196
£196 ÷ 7 = £28

Therefore, the reduced price of the cardigan is £28.

Conclusion

In this problem, we were given the original price of a cardigan as £49 and were asked to find the reduced price after a discount of 3/7. We used the concept of discounts and calculated the reduced price by multiplying the original price by the fraction of the discount. The reduced price of the cardigan is £28.
