Her statement is not reasonable because it is not true that 25% of female marathoners run 13 or more miles a week, it is true that 25% run less than 13 miles a week (out of the data). The rest of the data would be 75%, making the statement, "75% of female marathoners run 13 or more miles a week" true. The way she recorded the data does not interfere with the statement being reasonable since it is unbiased.
You multiply fractions simply by multiplying numerators and denominators with each other:
Hb=3.5, hd=2.25, hb+hd=7,
From the third, we can say hb=7-hd and we are told that:
3.5hb+2.25hd=19.5 using hb found above in this equation gives you:
3.5(7-hd)+2.25hd=19.5
24.5-3.5hd+2.25hd=19.5
-1.25hd=-5
hd=4
