There were
70
runners to start a race. in the first half of the race,
1/5
of them dropped out. in the second half of the race,
4/7
of the remaining runners dropped out. how many runners finished the race?

Hey there! So,to do this, I would recommend making the fractions into decimals. 1/5 is equal to 0.2 so you multiply that times 70 runners . This equals 14 runners who dropped out. Subtract those who dropped out from the total and now you have 56 runners left. 4/7 as a decimal is about 0.575. Times that by 56 and you get another 32 who dropped out. You're now down to only 24 runners who finished the race.

I'll say b) log(- that if not let me know what i can do
