Please help me :(
I need a step by step thing..​

Step-by-step explanation:

5/6×9

9=9/1

×=

plz can i get brainliest

7 1/2

To multiply a fraction, just multiply them.

In this problem, we'll multiplying a fraction by a whole number.

First off, convert 9 into a fraction by adding an one for the denominator.

Now 9 will be 9/1.

Second, apply the fraction rule.

Now, factor the number 9 and number 6.

9 = 3 × 3

6 = 2 × 3

Third, cancel the common factor 3.

Finally, you can solve.

5 × 3 = 15

2 will stay the same since there is nothing to multiply.

But your not done, your answer will be 15/2, but its improper. Now, you'll convert 15/2 to a mixed number.

You'll divide 15 by 2 using long division.

When done, your answer will be: 7 R 1.

7 is your whole number, and 1 will be represented as 1/2.

Hence, your answer is 7 1/2

Step-by-step explanation:

The n th term of an arithmetic sequence is

= a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Given a₁₂ = 38 and a₈₅ = 257 , then

a₁ +11d = 38 → (1)

a₁ + 84d = 257 → (2)

Subtract (1) from (2) term by term

73d = 219 ( divide both sides by 73 )

d = 3

Substitute d = 3 into (1)

a₁ + 11(3) = 38

a₁ + 33 = 38 ( subtract 33 from both sides )

a₁ = 5

Thus

5 + 3(n - 1) = 395 ( subtract 5 from both sides )

3(n - 1) = 390 ( divide both sides by 3 )

n - 1 = 130 ( add 1 to both sides )

n = 131

Thus there are 131 terms in the sequence
