Answer:56
Step-by-step explanation:
with 16 into 55 do that math then put the number you got then put it into another 16 boom 56
It equal to 24 because you have to multiply or divide first then you can add or subtract
Area= length times width. 10×6 is 60. Answer is 60 cm^2
His patio needs 56 stones because 8 multiplied by 7 equals 56. So if the paving stones are sold in batches of 12 (a dozen is equal to 12) then we need to find how many times 12 goes into 56. 12 cannot go into 56 evenly, but 12x5=60 which will be more than enough stones for Eric's patio. So Eric will need 5 batches of paving stones for his patio.
<u>Answer: </u>
clerk A and clerk B can simultaneously stock a shelf in 
minutes
<u>Explanation:</u>
Let the first clerk be A and the second clerk be B
A can stock a shelf in 20 min
B can stock a shelf in 45 min
Consider the complete work to be W
A’s rate of stocking = 
per minute
B’s rate of stocking = 
per minute
When, A and B work simultaneously, rate of work done = 
Total work done simulatenously = 
=
Therefore, clerk A and clerk B can simultaneously stock a shelf in minutes
