Estimate the sum. 6 1/5 plus 3 8/9 a.11 b.9 c.10 d.12

Hey there!

"Sum" means to add, so let's add the two fractions:

6 + 3 = 9

Find the LCD of both fractions . . .

1/5 = 9/45

8/9 = 40/45

9 + 40 = 49

= 49/45

Simplifying 49/45 . . .

49/45 = 1 4/45

1 + 9 = 10

= 10 4/45

6 1/5 + 3 8/9 = 10 4/45, but as an estimate the best answer will be 10. <---

Your answer is option "C."

Hope this helps you.
Have a great day! :)
