write 78 minutes to 2 hours as a ratio reduced in lowest terms
78/120 = 39/60 = 13/20
Sure, here's a ratio reduced to its lowest terms:
1 hour and 18 minutes : 2 hours
However, let's add some clown-ish humor to it:
Why did the 78 minutes go to therapy? Because it wanted to be reduced to its lowest terms and needed someone to talk it out with! It finally learned that it could have a positive ratio with 1 hour and 18 minutes to 2 hours. Those minutes are really learning to simplify their fractions!
To write 78 minutes to 2 hours as a ratio reduced to its lowest terms, we first need to convert both units to the same type. We can convert 2 hours into minutes since there are 60 minutes in 1 hour.
2 hours = 2 * 60 minutes = 120 minutes
Now we have:
78 minutes : 120 minutes
To reduce this ratio to its lowest terms, we need to find their greatest common divisor (GCD). In this case, the GCD of 78 and 120 is 6.
Dividing both numbers by 6:
78 ÷ 6 = 13
120 ÷ 6 = 20
Therefore, the ratio 78 minutes to 2 hours reduced to its lowest terms is:
13:20
To convert 78 minutes to hours, you divide it by 60 since there are 60 minutes in 1 hour:
78 minutes ÷ 60 = 1.3 hours
Now, to express this as a ratio, we compare the number of hours and minutes we have. Since we want to compare it to 2 hours, our ratio becomes:
1.3 hours : 2 hours
To find the ratio in its lowest terms, we need to simplify it. We can do this by dividing both numbers by their greatest common divisor (GCD).
The GCD of 1.3 and 2 is 0.1 (since 1.3 is equivalent to 1.3/1 and 2 is equivalent to 2/1).
Dividing both numbers by 0.1, we get:
1.3 ÷ 0.1 = 13
2 ÷ 0.1 = 20
So, the ratio of 78 minutes to 2 hours, reduced to its lowest terms, is:
13 : 20
