Pls convert 1 3/8 and 3 1/2 both into a decimal

Step-by-step explanation:

1) See below how to convert this mixed number to a decimal:

Step 1: divide numerator (3) by the denominator (8):

3 ÷ 8 = 0.375

Step 2: add this value to the the integer part:

1 + 0.375 = 1.375. So,

1 3/8 = 1.375

Approximated Values:

1 3/8 = 1 rounded to 1 significant figure

1 3/8 = 1.4 rounded to 2 significant figures

2) Step 1: divide numerator (1) by the denominator (2):

1 ÷ 2 = 0.5

Step 2: add this value to the the integer part:

3 + 0.5 = 3.5. So,

3 1/2 = 3.5.

c-4 is the final answer! : )

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
