To find the total number of candy bars, add Eliana and Kali's candy bar amounts:
Eliana: 2 ¾ = 2 + ¾ = 2 + (3/4) = 2 + 0.75 = 2.75
Kali: 5 2/8 = 5 + 2/8 = 5 + (1/4) = 5 + 0.25 = 5.25
Total candy bars = 2.75 + 5.25 = 8
There were 8 candy bars in the box. Answer: 8.
To find out how many candy bars were in the box, we need to add the number of candy bars Eliana ate with the number of candy bars Kali ate.
Eliana ate 2 ¾ candy bars, which is the same as 2 + ¾. To add these, we need to have the same denominator, which in this case is 4. So we can rewrite 2 as 8/4:
2 + ¾ = 8/4 + ¾ = 8/4 + 3/4 = 11/4
Therefore, Eliana ate a total of 11/4 candy bars.
Kali ate 5 2/8 candy bars, which is the same as 5 + 2/8. To add these, we need to have the same denominator, which in this case is 8. So we can rewrite 5 as 40/8:
5 + 2/8 = 40/8 + 2/8 = 42/8
Therefore, Kali ate a total of 42/8 candy bars.
To find out the total number of candy bars in the box, we need to add Eliana and Kali's totals:
11/4 + 42/8 = 22/8 + 42/8 = 64/8 = 8
Therefore, there were 8 candy bars in the box.
To find the total number of candy bars in the box, we need to add the amounts of candy bars that Eliana and Kali ate.
Eliana ate 2 ¾ candy bars, which can be written as 2 + ¾ = 2 + 3/4 = 8/4 + 3/4 = 11/4.
Kali ate 5 2/8 candy bars, which can be written as 5 + 2/8 = 5 + 1/4 = 20/4 + 1/4 = 21/4.
Now, let's add the amounts of candy bars they ate: 11/4 + 21/4 = 32/4 = 8.
Therefore, there were 8 candy bars in the box.
