Write the ratio as a fraction in simplest form. 51 correct : 9 incorrect

Write the ratio as a fraction in simplest form.

35 girls : 15 boys

51 correct : 9 incorrect = 17 correct / 9 incorrect

35 girls : 15 boys = 7 girls / 3 boys

Step-by-step explanation:

51 correct : 9 incorrect,

= 51 : 9

= 51 / 9

= 3 x 17 / 3 x 3

= 17 / 3

= 17 correct / 9 incorrect

35 girls : 15 boys

= 35 : 15

= 35 / 15

= 5 x 7 / 5 x 3

= 7 / 3

= 7 girls / 3 boys

see explanation

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

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24
