Step-by-step explanation:
1 hour = 60 minutes
40 minutes out of an hour can be written as: 40/60
Fraction = 40/60
= (2 × 30) / (3 × 20)
Canceling out common factors of numerator and denominator, we get 2/3
Therefore, 40 minutes is 2/3 of an hour.

What is the probability of landing on A then a C?* First Spin Second Spir С C E A B A DC
Answer:
Probability of landing on A: 25% chance
Probability of landing on C: 37.5% chance
Step-by-step explanation:
A. There are 2 A’s out of 8 letters which gives us a fraction of 2/8.
2/8 = 1/4 = 0.25 = 25%
C. There are 3 C’s out of 8 letters which gives us a fraction of 3/8.
3/8 = 0.375 = 37.5%
Hopefully this helped, good luck!

Janet can make 1/2 of a necklace in 20 minutes. At this rate, how many necklaces can Janet make in 2 hours?
Answer:
3 necklaces
Step-by-step explanation:
2 hours = 120 minutes
1 necklace in 40 minutes
120/40 = 3
3 necklaces
Answer:
3 necklaces
Step-by-step explanation:
2 hours needs to be in the same units as the 20 minutes
2 hours = 2 * 60 minute = 120 minutes
Now we can use ratios to solve
1/2 necklace x necklaces
-------------------- = ----------------
20 minutes 120 minutes
Using cross products
1/2 * 120 = 20x
60 = 20x
Divide by 20
60/20 = 20x/20
