Answer:
119
Step-by-step explanation:
Divide the number of baskets (56) by the denominator:
56 ÷ 8 = 7
Multiply by 7 to get the amount of 2 point baskets and multiply by 1 to get the amount of 3 point baskets. (they both add up to 56 baskets)
7 × 7 = 49
7 × 1 = 7
multiply the 49, 2 point baskets by 2 and the 7, 3 point baskets by 3 and add them together to get the total points.
49 × 2 = 98
7 × 3 = 21
98 + 21 = 119
It already is a decimal unless you mean a repeating decimal, it would be .26 with a line over the number.
