Answer:
415
Step-by-step explanation:
3 2/3 hours. Because if you do 2 3/4 times 1 1/3 you get 11/3 which simplifies into a mixed fraction of 3 2/3.
The product of 379 and 8 is 3,032.
It's between (any number less than 3,032) and (any number greater than 3,032).
I guess if this is an <em>estimation </em>exercise, you could say that it's between
(8 x 300) and (8 x 400), or 2,400 and 3,200.
To do this we take the outlier off the parenthesis (the 4) and multiply it by the two numbers inside the parenthesis...
4*7 + 4*8
28+32
300²+400²=500² is your answer
a²<span> + b</span>²<span> = c</span>²
