49 of his remaining pens to his brother and bought another 7 new pens. In the end, Cody had 22 pens.
- How many pens did Cody give to his brother?
- How many pens did Cody have at first?
(a)
Fraction of his remaining pens after he gave to his brother
= 1 -
49=
59 59 of his remaining pens = 22 - 7 = 15
19 of his remaining pens = 15 ÷ 5 = 3
49 of his remaining pens = 4 x 3 = 12
Number of pens that Cody gave to his brother = 12
(b)
99 of his remaining pens = 9 x 3 = 27
Fraction of his total pens after he gave to Rael
= 1 -
34=
14 14 of his total pens = 27 - 4 = 23
44 of his total pens = 4 x 23 = 92
Number of pens that Cody had at first = 92
