Answer 1

The expression 3/4 ÷ 2 1/2 can be used to solve problems that involve dividing a whole quantity (2 1/2) into smaller fractional portions (3/4). In this context, word problems b. and d. can be solved using this expression.

Step-by-step explanation:

Answering the original question posed, whether each problem can be solved by the expression 3/4 ÷ 2 1/2:

1. No, that problem is about subtraction, not division.
2. Yes, the expression given can be used to solve it since it involves division.
3. No, the division by 3/4 doesn't fit with this word problem.
4. Yes, since the expression is about finding how many 3/4 cups fit into 2 1/2 cup.

The expression 3/4 ÷ 2 1/2 works for problems where a whole (2 1/2) is divided into partial fraction portions (3/4). These include situations like determining how many smaller amounts (3/4) can fit into a larger quantity (2 1/2), as shown in examples b and d.
