Answer:
Step-by-step explanation:
Here we have the mixed numbers 1 5/8 and 9/10 and must sum them up to find the total number of miles Henry ran.
The LCD is 40: Note that 40 is evenly divisible by both 8 and 10.
We convert 1 5/8 into the improper fraction 13/8.
Then we rewrite 13/8 as 65/40 and 9/10 as 36/40; now both quantities have the denominator 40.
Adding 65/40 and 36/40 yields 101/40 miles total, or 2.525 miles.
