First she needs to estimate or guess what length they may be, like say the eraser is 2 1/2 inches, she then can use a ruler on the paper to get the actual length.
Answer:
m/3
Step-by-step explanation:
13 m or m 3
Explanation:One third = 13 (the number)'Of' = multiplication (symbol : ×)
a number m = m (variable)
One third of a number m= (one third)(a number m)= (13)(a variable) = (13)
(m)= 13 m or m 3 since 13 m = m/3
