Question
Albert walks 4/5 of a mile in 5/12 of an hour. Which expression can be used to find his unit rate in miles per hour?
Answers
GPT 3.5
To find Albert's unit rate in miles per hour, we can use the expression:
(4/5 miles) / (5/12 hours) = (4/5) / (5/12) = (4/5) * (12/5) = 48/25
Therefore, Albert's unit rate is 48/25 miles per hour.
(4/5 miles) / (5/12 hours) = (4/5) / (5/12) = (4/5) * (12/5) = 48/25
Therefore, Albert's unit rate is 48/25 miles per hour.
Which expression
4/5-5/12
5/12x4/5
5/12 divided by 4/5
4/5 divided by 5/12
4/5-5/12
5/12x4/5
5/12 divided by 4/5
4/5 divided by 5/12
GPT 3.5
Let's simplify each expression:
1. 4/5 - 5/12
To subtract fractions, we need a common denominator. The least common multiple of 5 and 12 is 60. So, we need to rewrite the fractions:
(4/5)*(12/12) - (5/12)*(5/5)
= 48/60 - 25/60
= (48 - 25)/60
= 23/60
2. 5/12 x 4/5
To multiply fractions:
(5/12)*(4/5)
= 20/60
= 1/3
3. 5/12 ÷ 4/5
To divide fractions, we multiply by the reciprocal of the second fraction:
(5/12) * (5/4)
= 25/48
4. 4/5 ÷ 5/12
Similarly, for this division:
(4/5) * (12/5)
= 48/25
Therefore,
1. 4/5 - 5/12 = 23/60
2. 5/12 x 4/5 = 1/3
3. 5/12 ÷ 4/5 = 25/48
4. 4/5 ÷ 5/12 = 48/25
1. 4/5 - 5/12
To subtract fractions, we need a common denominator. The least common multiple of 5 and 12 is 60. So, we need to rewrite the fractions:
(4/5)*(12/12) - (5/12)*(5/5)
= 48/60 - 25/60
= (48 - 25)/60
= 23/60
2. 5/12 x 4/5
To multiply fractions:
(5/12)*(4/5)
= 20/60
= 1/3
3. 5/12 ÷ 4/5
To divide fractions, we multiply by the reciprocal of the second fraction:
(5/12) * (5/4)
= 25/48
4. 4/5 ÷ 5/12
Similarly, for this division:
(4/5) * (12/5)
= 48/25
Therefore,
1. 4/5 - 5/12 = 23/60
2. 5/12 x 4/5 = 1/3
3. 5/12 ÷ 4/5 = 25/48
4. 4/5 ÷ 5/12 = 48/25
