Sasha is ordering balloons for a party. She wants to have a red and blue balloons with a ratio of 6 red to 10 blue. If she wants to purchase 300 balloons total, how many red balloons will she need to
purchase?

112.5 Red balloons

Step-by-step explanation:

6:10

We can set up a proportion to solve

6/6+10=6/16

6/16=x/300

16x=300*6

16x=1800

x=112.5

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
