The degree of an algebraic expression is the largest exponent of the variable present. In expressions with multiple variables, the exponents of each variables are added.
For #1, we have to divide four by (or 0.5), because that's the amount he gives his dog a day. For #2, we have to divide by two, because it is being split into two separate containers (0.5 ÷ 2 = 0.25, or ). #3 is a bit tougher. You can first write it as ÷ (because of gold are being split among seven people), then rewrite this as · . Three times one is three, four times seven is 28. So the final answer is . Hope this helps!
