Question

Coach Leonardo used altogether is:

9 1/2 + 2 2/5
To add these two fractions, you can first convert them to improper fractions:
9 1/2 = 19/2
2 2/5 = 12/5
Now, add the fractions:
(19/2) + (12/5)
To add fractions with different denominators, find a common denominator, which in this case is 10:
(19/2) + (12/5) = (19/2) * (5/5) + (12/5) * (2/2) = (95/10) + (24/10)
Now, add the fractions:
(95/10) + (24/10) = 119/10
So, Coach Leonardo used 119/10 meters of string altogether.
To make it a multiple-choice question:
Which expression could be used to determine the amount of string, in meters, Coach Leonardo used altogether?
a) 9 + 2 + 1/5 + 2/5
b) 9 + 2 + 5/10 + 4/10
c) 11 + 3/7
d) 11 + 3/10

Answer 1

To add two fractions, convert them to improper fractions, find a common denominator, and add the fractions. Coach Leonardo used 119/10 meters of string altogether.

Step-by-step explanation:

To add these two fractions, you can first convert them to improper fractions:

9 1/2 = 19/2
2 2/5 = 12/5

Now, add the fractions:

(19/2) + (12/5)

To add fractions with different denominators, find a common denominator, which in this case is 10:

(19/2) + (12/5) = (19/2) * (5/5) + (12/5) * (2/2) = (95/10) + (24/10)

Now, add the fractions:

(95/10) + (24/10) = 119/10

So, Coach Leonardo used 119/10 meters of string altogether.
