Explain how you know that 5/8 + 6/10 is greater then 1
WARRIOR [948]

Step-by-step explanation:

So you would need to find a common denominator to add the fractions together first, and the closest would be 40

5/8 turns into 25/40 because we times the bottom and the top by 5 to get the LCD (least common denominator)

6/10 turns into 24/40 when times by 4 for the LCD of 40

Then add them together: 25/40 + 24/40 = 49/40

And since 1 could also be written as 40/40 since that is the whole number, this means the following expression is true.

49/40 > 40/40 (or 1)
