Total number of buttons that Olivia and Opal shared = 100%
If Olivia gave 56 buttons to Opal, both would have the same number of buttons.
Number of buttons that each would have in the end
= 100% ÷ 2
= 50%
Number of buttons that Olivia gave to Opal
= 78% - 50%
= 28%
28% → 56
1% → 56 ÷ 28 = 2
Number of buttons that Opal had
= 22%
= 22 x 2
= 44
Answer(s): 44
