Write the following number words into number symbols. (1 point per item=5 points) (5minutes) 1.) Two hundred billion, one hundred million, six hundred twenty thousand, two hundred sixty-one. 2.) Eight hundred fifty-two thousand, six hundred seventy-four and thirty-five hundredths. 3.) Forty percent of N is equal to two hundred forty. 4.) three and one-half 5.) four is to eight
The Correct Answer and Explanation is:
Here are the number words written in number symbols:
- Two hundred billion, one hundred million, six hundred twenty thousand, two hundred sixty-one
This can be written as:
200,100,620,261Explanation: The number is broken down as follows:- “Two hundred billion” = 200,000,000,000
- “One hundred million” = 100,000,000
- “Six hundred twenty thousand” = 620,000
- “Two hundred sixty-one” = 261
So, combining these, we get 200,100,620,261.
- Eight hundred fifty-two thousand, six hundred seventy-four and thirty-five hundredths
This can be written as:
852,674.35Explanation:- “Eight hundred fifty-two thousand” = 852,000
- “Six hundred seventy-four” = 674
- “And thirty-five hundredths” = 0.35 (since “hundredths” means two decimal places)
So, the complete number is 852,674.35.
- Forty percent of N is equal to two hundred forty
This can be written as:
0.40 * N = 240Explanation:- “Forty percent” = 40% = 0.40 (as a decimal)
- “of N” represents the multiplication with variable N
- “is equal to” translates to the equality sign =
- “Two hundred forty” is written as 240
So the equation is 0.40 * N = 240.
- Three and one-half
This can be written as:
3.5Explanation:- “Three” is the whole number 3
- “And one-half” means adding 1/2, or 0.5, to the whole number
So, it becomes 3.5.
- Four is to eight
This can be written as:
4:8 or 4/8Explanation:- “Four is to eight” represents a ratio or fraction
- It can be written as 4:8 (ratio) or 4/8 (fraction)
Simplified, the ratio or fraction can be reduced to 1:2 or 1/2.
These are the correct number symbols for the given number words.
