Estimate the sum. 6 1/5 plus 3 8/9 a.11b.9c.10d.12
Question
Answer:
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! :)
