Answer:
1. 8 days
2. [tex]\frac{1}{4}[/tex] pound
3. [tex]\frac{3}{28}[/tex] grams
Step-by-step explanation:
For #1, we have to divide four by [tex]\frac{1}{2}[/tex] (or 0.5), because that's the amount he gives his dog a day. For #2, we have to divide [tex]\frac{1}{2}[/tex] by two, because it is being split into two separate containers (0.5 ÷ 2 = 0.25, or [tex]\frac{1}{4}[/tex]). #3 is a bit tougher. You can first write it as [tex]\frac{3}{4}[/tex] ÷ [tex]\frac{7}{1}[/tex] (because [tex]\frac{3}{4}[/tex] of gold are being split among seven people), then rewrite this as [tex]\frac{3}{4}[/tex] · [tex]\frac{1}{7}[/tex]. Three times one is three, four times seven is 28. So the final answer is [tex]\frac{3}{28}[/tex]. Hope this helps! Feel free to ask any questions :)
