Question

Linda can complete 4.5 long divisions in 1 hour. How many can she finish in 6.5 hours?

Answer 1

29.25

Because 4.5 x 6.5 = 29.25

Answer 2

29.25 is the answer. 
If she can do 4.5 in one hour, then in order to find out how many she can do in 6.5 hours, you need to multiply the two numbers together. 4.5 x 6.5 = 29.25
