The ratio of points scored by Jennie, Sarah, and Sadie in the basketball games played last week was 1: 3: 5. If Jennie scored 10 points last week. What was the total number of points scored by these three girls?
If Jennie is the first number in the ration then 1=10 because the ratio shows as her having one and we know she scored ten. If we add 5+3+1 we get 9. Since we know that one equals ten we can multiply 9*10 and get 90 points total.
