Grace and Caleb had a total of 207 buttons. Caleb had 2 times as many buttons as Grace.
- How many buttons did Grace have?
- How many buttons did Caleb have?
(a)
Number of buttons that Grace had = 1 u
Number of buttons that Caleb had = 2 u
Total number of buttons
= 2 u + 1 u
= 3 u
3 u = 207
1 u = 207 ÷ 3 = 69
Number of buttons that Grace had
= 1 u
= 69
(b)
Number of buttons that Caleb had
= 2 u
= 2 x 69
= 138
Answer(s): (a) 69; (b) 138
