The temperature in Antarctica at noon is 14°F. By 9:00PM, the temperature had dropped by 16.2 degrees. What was the temperature at 9:00PM?
9 answers
The temperature at 9:00 PM would be 14°F - 16.2°F = -2.2°F.
Consider this expression:
1/4 − 0.5 + 1/2 − 0.25 + 3/5+ 0.4
Question 1
You are asked to find the sum by using fractions. Which expression could you use?
1/4 − 0.5 + 1/2 − 0.25 + 3/5+ 0.4
Question 1
You are asked to find the sum by using fractions. Which expression could you use?
To find the sum by using fractions, you can use the expression:
1/4 + 1/2 + 3/5.
1/4 + 1/2 + 3/5.
then find the sum
To find the sum of 1/4 + 1/2 + 3/5, we need to find a common denominator for the fractions. The least common denominator (LCD) for 4, 2, and 5 is 20.
Now, we can rewrite the fractions with the common denominator:
(1/4) * (5/5) + (1/2) * (10/10) + (3/5) * (4/4)
= 5/20 + 10/20 + 12/20
Combining the numerators, we get:
= (5 + 10 + 12) / 20
= 27/20
Therefore, the sum of 1/4 + 1/2 + 3/5 is 27/20.
Now, we can rewrite the fractions with the common denominator:
(1/4) * (5/5) + (1/2) * (10/10) + (3/5) * (4/4)
= 5/20 + 10/20 + 12/20
Combining the numerators, we get:
= (5 + 10 + 12) / 20
= 27/20
Therefore, the sum of 1/4 + 1/2 + 3/5 is 27/20.
simplify
To simplify the fraction 27/20, we can find the greatest common divisor (GCD) of the numerator and denominator, which is 9. Then, we can divide both the numerator and denominator by 9.
27 ÷ 9 = 3
20 ÷ 9 = 2 remainder 2
Therefore, 27/20 simplifies to
3 + 2/20
Since 2/20 can be simplified further by dividing both numerator and denominator by 2, we get:
3 + 1/10.
So, 27/20 simplifies to 3 + 1/10.
27 ÷ 9 = 3
20 ÷ 9 = 2 remainder 2
Therefore, 27/20 simplifies to
3 + 2/20
Since 2/20 can be simplified further by dividing both numerator and denominator by 2, we get:
3 + 1/10.
So, 27/20 simplifies to 3 + 1/10.
