Henry and Jen share some pens.
25 of Henry's pens is equal to
27 of Jen's pens. Given that Henry has 18 pens less than Jen, how many pens do they have altogether?
25 of Henry's pens = 27 of Jen's pens
Number of Henry's pens = 5 u
Number of Jen's pens = 7 u
Number of pens that Henry has less than Jen
= 7 u - 5 u
= 2 u
2 u = 18
1 u = 18 ÷ 2 = 9
Total number of pens
= 5 u + 7 u
= 12 u
= 12 x 9
= 108
Answer(s): 108
