What's bigger 2/3 or 4/5

Answers

The best thing to do is either to find a common denominator or convert them to decimals.
I will find a common denominator.
A common denominator of 3 and 5 is 15.
You multiply the first fraction by 5
2*5= 10
This then becomes 10/15
You then multiply the second by 3.
4*3= 12
Therefore, this becomes 12/15
As the second of these fractions is larger, this means that 4/5 is larger.
The alternative method is to put them into decimals, in which case 2/3= 0.66 and 4/5= 0.8
Hope this helps :)

find the LCD (15) and change the fractions to: 10/15 and 12/15. compare the numerators, 12 is greater, so **4/5** is greatest

Explain how to estimate 245 ÷ 41 by using rounding and then find the estimate

Answers

41 is able to be rounded down to 40, so divide 245 by 40 and you get about 6 and 1/2. So to compare that with the original, it would be a bit less than 6.5, so about 6.3 or 6.4

Answer:

Step-by-step explanation:

Normal

245÷4=61.25
