Answers & Comments
Answer:
a.) What part of the participants are male teachers?
b.) 4/5 of the participants are teachers and 3/8 of the teachers are male
c.) Subtraction
d.) 4/5 - 3/8 = x
e.) Get the LCD which is 40.
Then, 32/40 - 15/40 = x.
Therefore, x = 17/40.
f.) Checking:
So, 17/40 + 3/8 = 4/5?
17/40 + 15/40 = 32/40?
32/40 = 32/40
Yes, the operation is used correctly and the answer is reasonable.
g.) 17/40 of the participants are male teachers.
