Tom and Hazel share some pens.
611 of Tom's pens is equal to
613 of Hazel's pens. Given that Tom has 12 pens less than Hazel, how many pens do they have altogether?
611 of Tom's pens = 613 of Hazel's pens
Number of Tom's pens = 11 u
Number of Hazel's pens = 13 u
Number of pens that Tom has less than Hazel
= 13 u - 11 u
= 2 u
2 u = 12
1 u = 12 ÷ 2 = 6
Total number of pens
= 11 u + 13 u
= 24 u
= 24 x 6
= 144
Answer(s): 144
