49 of his remaining pens to his sister and bought another 7 new pens. In the end, Cole had 42 pens.
- How many pens did Cole give to his sister?
- How many pens did Cole have at first?
(a)
Fraction of his remaining pens after he gave to his sister
= 1 -
49=
59 59 of his remaining pens = 42 - 7 = 35
19 of his remaining pens = 35 ÷ 5 = 7
49 of his remaining pens = 4 x 7 = 28
Number of pens that Cole gave to his sister = 28
(b)
99 of his remaining pens = 9 x 7 = 63
Fraction of his total pens after he gave to Fabian
= 1 -
23=
13 13 of his total pens = 63 - 4 = 59
33 of his total pens = 3 x 59 = 177
Number of pens that Cole had at first = 177
