Answer 1

Let's break out one by one number by their standup values

• 2=10000
• 7=1000
• 3=100
• 8=10
• 5=1

Turn = to × and add all

`\\ \rm\rightarrowtail 2* 10000+7* 1000+3* 100+8* 10+5`

Answer 2

A

Explanation:

Every digit of a number has a place value. Place value is the value represented by a digit in a number based on its position in the number.

In the number 27,385:

2 is in ten thousands place ⇒ 2 × 10,000 so its place value is 20,000

7 is in thousands place ⇒ 7 × 1,000 so its place value is 7,000

3 is in hundreds place ⇒ 3 × 100 so its place value is 300

8 is in tens place ⇒ 8 × 10 so its place value is 80

5 is in units place so its place value is 5

Therefore,

27,385 = 2 × 10,000 + 7 × 1,000 + 3 × 100 + 8 × 10 + 5

So the answer is A
