Samuel needs to estimate the product of 24 x 395.
First method
We round the number to nearest tens
24 can be rounded to 20 because we have 4 on ones place
395 can be rounded to 400 because we have 5 in ones place so we add 1 with 9 and it becomes 10 . so we add 1 with 3 and got 400
20 * 400 = 8000
Second method:
We round the number to nearest hundreds place
24 have no number in hundreds place so it remains 24
395 can be rounded to 400 because we have 9 in tens place.
24 * 400 = 9600
I don't understand your question
Answer:
Both processes are correct.
Step-by-step explanation:
Let the mile taken by Chase be 10miles .
He doubles it so it will be 20 and
20% of 20 will be 4
20-4 = 16km
Now Alex operations
(10/5 )*8 = 2*8= 16 km
In both cases the answer will be the same
1 mile = 1.60034 km
Now 10 miles = 16.00 34 km
which is the same as above.
Both the processes are correct.
20% is .20/ 20/50 is 40% or .4 or 4/10/ 9% is .09 or 9/100 / 9/10 is 90% or .9/ 66% is .66 or 33/50 or 66/100/ 6/10 is 60% or 60/100 or .6/ 2% is .02 or 1/50 or 2/100. I didn't exactly understand the question, but I hope this answers your question.
