We have two fractions, 1/6 and 3/8, and we want to rewrite them so that they have a common denominator (and whole number numerators). What numbers could we use for the denominator?

Answers

Answer 1

Answer:

Answer:

12,24 etc

Step-by-step explanation:4 and 6 both go into 12 evenly

4*3 = 12

6*2 = 12

12 is the least common denominator

We could also use 24

4*6 = 24

It is a common denominator, but not the least common denominator

We can use any multiple of 12

How would you round off a number to one decimal place? For example would 67.39 become 67.4

Answers

you take the second decimal, and if it is 5 or over, you increase the first decimal by one. If the number is 17.96,you increase the first decimal by one which gives you 18. If the question asks for 1 decimal place, than put 18.0 :)

when rounding off numbers to specific decimal places look at the number after that place. If that number is less than 5 then keep the needed decimal the same. if it is greater than 5 then round up by one.

Examples:

15.69 ⇒ 15.7
15.64 ⇒ 15.6

17.890 ⇒ 17.89
17.898 ⇒ 17.90
