Solution

Solution Steps

Step 1: Writing the Number in Digits

The number "Four hundred twenty-five and five thousandths" is written as $425.005$. The correct option is d. 425.05.

Step 2: Writing in Standard Notation

The expression $(9 \times 100,000) + (2 \times 1,000) + (4 \times 1) + (7 \times 0.01)$ simplifies as follows:

$9 \times 100,000 = 900,000$
$2 \times 1,000 = 2,000$
$4 \times 1 = 4$
$7 \times 0.01 = 0.07$ Adding these together gives $902,004.07$. The correct option is b. 902,004.07.

Step 3: Identifying Number Sets for $\sqrt{49}$

$\sqrt{49} = 7$. The number 7 belongs to:

Natural numbers ($\mathbb{N}$)
Whole numbers ($\mathbb{W}$)
Integers ($\mathbb{Z}$)
Rational numbers ($\mathbb{Q}$)
Real numbers ($\mathbb{R}$) The correct option is e. It belongs to A, B, and C.
