Hello good person! When you're rounding, numbers 1-4 will keep the number the same. Numbers 5-9 will make it go up one number, so the number would be 96. Hope this helps!
The 3rd one, just work out the values- 0.5, 5, 5.22, 6.5
Since we know 16 ounces equal a pound, we just need to divide 72 by 16.
72/16 = 4.5
Your answer should be 4.5 pounds. Hope this helps!
