Answer: 3/8
Explanation: To subtract unlike fractions such as 5/8 - 1/4, first find a common denominator. The common denominator of 8 and 4 will be the least common multiple of 8 and 4 which is 8.
Notice that our first fraction already has 8 in the denominator so it stays the same. To get 8 in the denominator of 1/4, we multiply the numerator and denominator by 2 to get 2/8.
Now we have 5/8 - 2/8.
To subtract like fractions, we simply subtract the numerators to get 3 and keep our denominator of 8 and we have 3/8.
Since 3/8 is in lowest terms, it's our final answer.
Therefore, 5/8 - 1/4 = 3/8.
Answer:
300 calories
Step-by-step explanation:
he burns 12 calories each lap so you need to know how many laps he ran
which means you need to find the circumference of the track, whose formula is 2πr; remember, radius is half the diameter.
C = 2π75
C = 150π
C ≈ 471
Now divide the total number of feet he ran (11,775) by the circumference to arrive at the number of laps.
11775 ÷ 471 = 25 laps
25 x 12 = 300 calories burned in total
