Answer 1

Given :- On the track and field team, 3/ 8 of the members do the hurdles. Of the members who do the hurdles, 4 /5 also do the long jump. If there are 40 members on the track team, how many do both the hurdles and the long jump ?

Solution :-

we have ,

→ Total members = 40 .

now, Out of 40 members, (3/8) of the members do the hurdles .

So ,

→ Members who do hurdles are = (3/8) of 40 = (3/8) * 40 = 15 members .

Now, we have given that, members who do the hurdles, 4 /5 also do the long jump .

So,

Answer 2

As there are 40 members on the track team,

if 3/8 of them do the hurdles, we have to divide 40 by 8 and the multiply the result by 3 to know the number.

So, 40 / 8 is 5, and 5 x 3 is 15.

Therefore, 15 members do the hurdles.

Of the members who do the hurdles, 4/5 of them also do the long jump
