With rounding:
is less than
so we round it down to whole number:
is more than
so we round it up to whole number:
Now we have to add rounded numbers
Without rounding:
to make it more visible I will write it differently:
is equal to
we can see that
is equal to
so:
<span>As you see in this example those equations are equal so it doesn't matter if you take rounded numbers or not, it may be different in case like
(
is just an example it could be any other number between
) because in this case it will be equal
and another example
(in this case
is just an example, it can be any other number between
:) ) and here, answer for this equation is

Answer:
1. >
2. <
3. =
Step-by-step explanation:
100x8=800, 4*7=28, multiplied by 25 is 700, therefore making 800 greater than 700. Whenever comparing two multiplication problems, multiplying large numbers produces large results, so whichever starts larger will have an end result that is larger. 100 was large and it is smaller to its counter 25.
36 elevens really means 11x36, which is 396. 40 elevens really means 40x11, which is 440 minus 11x3 which is 407. 407 is greater than 396. The same logic applies here as the previous answer, the only difference is that the removal of three elevens is still larger than 36 elevens in this case.
12x24=288, 6x24=144, doubled makes it 288. In this case, the six is half of the twelve to begin with and then is made up for later by the fact that it is doubled.
When I solve math questions like these, I ignore the fact that it doesn't want a mathematical answer, do the math anyway and pull logic from it. (If your teacher checks, do it on a separate piece of paper, and then toss it.)
Answer:
40
Step-by-step explanation:
do 320=8t
divide 320 by 8 to isolate t
t = 40
Answer:
125 is the value of the question
Answer:
49.73
Step-by-step explanation:
You make the fractions into decimals and get 9.5 and 7.3. Then multiply those by the price given to get $23.75 and 25.98. When you add those numbers together you get $49.73.
