How it can help is if you have one side of a rectangle like 4.2342323332 and you had to multiply it by 2.8493844, that would be too hard so you could just make it into 4x2 which equals 8

He gets two pieces.

Next, he cuts each of the pieces into three parts.

$2 \div \frac{1}{3} = 6$

Thirdly, he cuts each of the 6 pieces into 8 pieces.

$6 \div \frac{1}{8} = 48$

Lastly, he divides each piece into 16 parts.

$48 \div \frac{1}{16} = 768$

He has 768 pieces in the end. (D)

const2013 [10]

Answer:

A) Yes, 7

Step-by-step explanation:

The given sequence An = {13, 20, 27, 34, ...}

Here the first term Ao = 13 and difference between the successive terms is (d) = 7

That is d = 20 - 13

d = 7

It is an arithmetic sequence. d = 7

Answer: Yes, it is arithmetic sequence and common difference (d) = 7

Thank you.
