A drought can cause the level of the local water supply to drop by a few inches each week.Suppose the level of the water supply drops 2.8 inches each week A. how far will it have dropped in 4 weeks. B. How far will it have dropped in 6 half weeks C. Create another real world situation which is not a water supply drought,using the numbers -2.8 and 4. its multiplying rational numbers
If the water level drops 2.8 inches in 1 week, then you can construct the table below: Week Water drop 1 2.8 = 1 * 2.8 = 2.8 2 2.8 + 2.8 = 2 * 2.8 = 5.6 3 5.6 + 2.8 = 2.8 + 2.8 + 2.8 = 3 * 2.8 = 8.4 4 8.4 + 2.8 = 2.8 + 2.8 + 2.8 + 2.8 = 4 * 2.8 = 11.2 You see that part A is a multiplication problem. The water level drops 2.8 inches in 1 week, so to find how much it drops in any number of weeks, multiply the number of weeks by 2.8.
For part B, all you need to do is multiply the number of weeks by the drop, 2.8. First, how many weeks is 6 half weeks? Figure that out then multiply it by 2.8.
