A teacher asked his three students Tom, Helen and Sandy to
complete 200 exercises. The ratio of the exercises completed
by Tom to the exercises completed by Helen to the exercises
completed by Sandy is 3:3:4. Tom receives 5 points for each
completed exercise. Sandy receives 8 points for each exercise.
If the three students altogether receive 1240 points, how many
points does Helen receive for a completed exercise?
points

5 point

Step-by-step explanation:

dividing the ratio

200/3+3+4=200/10=20

# of exercises

T 3 x 20=60

H 3 x 20=60

S 4 x 20=80

# of points

T60 x 5=300

H 60x 5=300

S 80 x 8=640

total points: 1240

So Helen recieved 5 points for each exercise completed

becaseu tom and helen have the same ratio
