1. **State the problem:** We are given the weights of a diabetic patient for the first four days in stones and pounds: 10st 10lbs, 9st 6lbs, 8st 6lbs, and 7st 12lbs. We want to understand or analyze these weights, possibly converting them into a consistent unit. 2. **Recall the conversion rule:** 1 stone (st) = 14 pounds (lbs). 3. **Convert each weight to pounds:** - Day 1: $10 \text{st} 10 \text{lbs} = 10 \times 14 + 10 = 140 + 10 = 150$ lbs - Day 2: $9 \text{st} 6 \text{lbs} = 9 \times 14 + 6 = 126 + 6 = 132$ lbs - Day 3: $8 \text{st} 6 \text{lbs} = 8 \times 14 + 6 = 112 + 6 = 118$ lbs - Day 4: $7 \text{st} 12 \text{lbs} = 7 \times 14 + 12 = 98 + 12 = 110$ lbs 4. **Interpretation:** The patient's weight is decreasing over the four days: 150 lbs, 132 lbs, 118 lbs, and 110 lbs. This conversion helps in comparing weights easily or performing further calculations if needed.
