Answer:
The total number of points scored is 60.
Step-by-step explanation:
We can multiply a number to both fractions to get them to share a common denominator so we can add them easily. 20 is a multiple of both 4 and 5, so let us multiply both denominators so that they each have a denominator of 20.
1/10 * 2 = 2/20
1/4 * 5 = 5/20
Now we can add those fractions together because we want to see the total amount of points the team scored.
2/20 + 5/20 = 7/20
If 7/20 is 21 points, we can find out how much points takes up 1/20 of the fraction. We do this by dividing 21 by 7.
21 / 7 = 3
So 1/20 = 3
Now we multiply 3 by 20, which is 60. So therefore the total amount of points scored by the team is 60. Brian scored 1/10 of 60, which is 6. So he scored 6 points. Joe scored 1/4 of 60, which is 15. So Joe scored 15 points. Hope this helps.
