Answer: Team one = 1/5
Team 2 = 4/21
Team A is the fastest
Step-by-step explanation: Answer: Team one = 1/5
Team 2 = 4/21
Team A is the fastest
Step-by-step explanation: TEAM A
Tammy working alone in 1hr can clean 1/2
Melissa working alone in 1 hr can clean 1/3
working together in 1hr ,let x represent the area they will clean we have
[tex]\frac{1}{1/2}[/tex] + [tex]\frac{1}{1/3}[/tex] = 1/x
⇒ 3 + 2 = 1/x
5 = 1/x
x = 1/5
TEAM B
Santay working alone can clean 1/4
Leticia working alone in 1 hr can clean 4/5
working together in 1 hr ,let y represent the amount they clean, we have
[tex]\frac{1}{1/4}[/tex] + [tex]\frac{1}{4/5}[/tex] = 1/y
4 + 5/4 = 1/y
21/4 = 1/y
y = 4 /21
comparing x and y , 1/5 is greater than 4/21 , therefore Team A is faster
Answer:
Team 1 cleaned 5/6 of their area in an hour, and team 2 cleaned 1 1/20 of their area in an hour. Therefore, team 2 was fastest
Step-by-step explanation:
general:
least common multiple of 2 (1/2), 3 (1/3), 4 (1/4), and 5 (4/5) is 60.
team 1:
using the LCM (60) we multiply 1/2 by 30 to get 30/60 and 1/3 by 20 to get 20/60. 20/60 + 30/60 = 50/60 = 5/6
team 2:
Using the LCM (60) we multiply 1/4 by 15 to get 15/60, and 4/5 by 12 to get 48/60. 48/60 + 15/60 = 63/60 = 1 3/60 = 1 1/20
