Mrs. Brock's class has 23 students. Each student has 8 markers. Which describes how to find the total number of markers in the class?
a) Multiply the ones. Record;
b) Multiply the tens. Record;
c) Multiply the tens. Record. Multiply the ones. Record. Add the partial products. Record.
d) Multiply the ones. Record. Multiply the tens. Record. Subtract the partial products. Record.
The correct option to find the total number of markers in Mrs. Brock's class is c) Multiply the tens. Record. Multiply the ones. Record. Add the partial products. Record.
To explain the process:
1. Start by multiplying the tens digit of the number of students (2) by the number of markers each student has (8). This gives us the partial product of 16 (2 x 8 = 16).
2. Next, multiply the ones digit of the number of students (3) by the number of markers each student has (8). This gives us another partial product of 24 (3 x 8 = 24).
3. Finally, add the two partial products together: 16 + 24 = 40.
Therefore, the total number of markers in Mrs. Brock's class is 40.
