First we take the number as it is. Second, we look at the last number. 6 is rounds up to ten which rounds the 3 up to a 4. So now we come up with 8.4, but that isn't a whole number. We can then round 4 to 0 because it's closer to 0 on a number line. Now, our answer is 8.0, but, in order to have a whole number, we can't have any decimals. we can, then, take away the 0 and the decimal, which leaves us 8, and 8 is a whole number; we can now say the answer is 8. :)
Answer:
150x46=6,900
Step-by-step explanation:
Answer:
7 times during the first 15 minutes
Step-by-step explanation:
Remember that
so
Decompose the numbers 18 and 42 in prime factors
we know that
Find the least common multiple (LCM)
The LCM is
we need to find all multiples of 126 that are less than or equal 900.
therefore
7 times during the first 15 minutes
20 and 24 are the answers
