Mr. Martanarie bought a new lamp and lamppost for his home. The pole was 6 5/8 ft tall and the lamp was 1 1/4 ft in height. How tall were the lamp and post together?
You're welcome, Laruen.
Add 6 5/8 + 1 2/8.
i know that's what I just realize
thank you ms. sue! :)
To find the total height of the lamp and post together, you need to add the heights of the lamp and post.
First, convert the mixed numbers to improper fractions for easier calculation:
- The height of the pole is 6 5/8 ft. To convert this to an improper fraction, multiply the whole number, 6, by the denominator, 8, and add the numerator, 5. The result is 53/8 ft.
- The height of the lamp is 1 1/4 ft. To convert this to an improper fraction, multiply the whole number, 1, by the denominator, 4, and add the numerator, 1. The result is 5/4 ft.
Now, add the heights of the lamp and pole:
53/8 ft + 5/4 ft
Since the denominators are different, you need to find a common denominator. The least common multiple (LCM) of 8 and 4 is 8.
To make the denominators the same, multiply the numerator and denominator of 5/4 by 2:
53/8 ft + (5/4 ft x 2/2)
Now the calculation becomes:
53/8 ft + 10/8 ft
To sum the fractions, add the numerators together and keep the denominator the same:
(53 + 10)/8 ft
The sum is:
63/8 ft
To simplify the improper fraction, divide the numerator, 63, by the denominator, 8, and express any remainder as a mixed number:
63 รท 8 = 7 remainder 7
Therefore, the total height of the lamp and post together is 7 7/8 ft.
