Please help especially with a. thank you!!

a) 25/324

b) 1/4

c) 1/3

Step-by-step explanation:

a) [⅓A + ⅓B]² = (⅓)²[A + B]²

= (1/9) [½ + ⅓]²

= (1/9)(⅚)²

= (1/9)(25/36)

= 25/324

b) ½ × ½ = ¼

c) (½ × ⅓) + (⅓ × ½) = 2 × ⅙ = ⅓

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.

the correct answer is 1: 2

step-by-step explanation:

hope this your welcome : )
