A number line starts with 7 and ends with 9.There are 7 marks in between. The letter A is above the 5th mark. What is the value of A as a fraction
The number 8 should be at the 4th mark.
It looks like each mark represents 1/4.
Can you find A now
8 1/4
To find the value of A as a fraction, we first need to determine the size of the interval between each mark on the number line.
The number line starts with 7 and ends with 9, with 7 marks in between. This means there are a total of 7 + 1 = 8 equal intervals between each mark.
To find the size of each interval, we can subtract the starting point of the number line (7) from the ending point (9) and divide it by the number of intervals (8 - 1 = 7):
Interval size = (Ending point - Starting point) / Number of intervals
= (9 - 7) / 7
= 2 / 7
Now that we know the size of each interval, we can determine the position of the letter A. The question states that A is above the 5th mark.
Counting from the starting point, we find that the 5th mark is 5 intervals away:
5th mark position = 5 * Interval size
= 5 * (2 / 7)
= 10 / 7
Therefore, the value of A as a fraction is 10/7.
