Question

drag each symbol to the correct location on the equation. not all symbols will be used.
a group of third - grade and fourth - grade students are taking a field trip. the group will use a total of 4 vans to take them on the field trip. each van seats 8 students.

• there are 27 third - grade students in the group.
• the rest of the students in the group are fourth - graders.

complete the equation to show how to find f, the number of fourth - grade students in the group.
symbols: +, ×, −, +
numbers: 4, 8, 27, = f

Explanation:

Step1: Calculate total seats

Each van seats 8, and there are 4 vans. So total seats (total students) is \(4 \times 8\).
\(4 \times 8 = 32\)

Step2: Find fourth - graders

Total students are \(4\times8\), and third - graders are 27. So fourth - graders \(f=4\times8 - 27\).
So the equation is \(27+ f=4\times8\) (or \(f + 27=4\times8\)) or rearranged as \(f=4\times8 - 27\).

Answer:

The equation is \(f + 27=4\times8\) (or \(27 + f=4\times8\) or \(f=4\times8 - 27\)). If we calculate \(f\), \(f = 32-27=5\). But for the equation construction, using the symbols given (assuming we need to put in the blanks: the first operation is \(\times\) between 4 and 8, then \(-\) with 27, and \(=\) with \(f\) or arranging as \(27 + f=4\times8\) with \(+\) between 27 and \(f\) and \(\times\) between 4 and 8). So the filled equation could be \(27 + f=4\times8\) (with \(+\) between 27 and \(f\), \(\times\) between 4 and 8).
