What is the difference in the price of 300cm of ribbon between shop A and B.      A: 148cm cost : £1.68.         B:215cm cost: £1.72

To find the difference in the price of 300 cm of ribbon between Shop A and Shop B, we'll calculate the cost per centimeter for each shop and then determine the cost of 300 cm at each shop.

### Step 1: Calculate the cost per centimeter for each shop.

#### Shop A:
- Price for 148 cm = £1.68
- Cost per cm = \( \frac{1.68}{148} \approx 0.01135 \) £/cm

#### Shop B:
- Price for 215 cm = £1.72
- Cost per cm = \( \frac{1.72}{215} \approx 0.008 \) £/cm

### Step 2: Calculate the cost of 300 cm for each shop.

#### Shop A:
- Cost for 300 cm = \( 0.01135 \times 300 \approx 3.405 \) £

#### Shop B:
- Cost for 300 cm = \( 0.008 \times 300 = 2.4 \) £

### Step 3: Find the difference in cost.

Difference = Cost at Shop A - Cost at Shop B  
Difference = \( 3.405 - 2.4 = 1.005 \) £

So, the difference in price for 300 cm of ribbon between Shop A and Shop B is approximately **£1.01**.
