Express each ratio as a fraction in simplest form 16 feet out of 40 feet

Step-by-step explanation:

Start by dividing top and bottom by 4

16 / 4 = 4

40/4 = 10

The result so far is 4/10

But 4/10 is not the answer. You can divide 4 and 10 by 2

4/2 = 2

10/2 = 5

2/5

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
