Answer:
18/5
Step-by-step explanation:
From my understanding, this is 1 whole 2 upon 10
Step 1: Convert mixed fraction into fraction
Multiply whole number by denominator: 1 x 10 = 10
Add numerator: 10 + 2 = 12
Write the result as the numerator and use the same denominator.
12/10
Step 2: Find the total tape used
From my understanding, each student used 12/10 of the tap
So 3 students used: 12/10 x 3 = 18/5
Therefore, the total tape used for three students was 18/5.
