Lliana was part of a group that was working on changing 0.4 to fraction. each member o the group had a different answer. which answer is correct? a) 2/5b) 4/10

Both are correct.

A) A decimal fraction

B) A common fraction

Step-by-step explanation:

1 step. Write down 0.4 divided by 1:

2 step. Multiply both top and bottom by 10 (because there are 1 digit after the decimal point):

This fraction is called a decimal fraction.

3 step. Simplify the decimal fraction:

This fraction is called a common fraction.

e) none of the above because the measure of angle cba is 101°

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
