Which digit in 1,377,207 has a value that is 1/10 the value of the 7 in the ten thousand place?
Nesterboy [21]

Considering the values of the digits in the number, we have that digit 2 has a value that is 1/10 the value of the 7 in the ten thousand place.

<h3>What are the values of the digits in the number 1,377,207?</h3>

We start counting the values from the final number, from 1 and multiplying by 10, hence:

  • Digit 7 has a value of 1.
  • Digit 0 has a value of 10.
  • Digit 2 has a value of 100.
  • Digit 7 has a value of 1,000.
  • Digit 7 has a value of 10,000. -> Ten thousand place.
  • Digit 3 has a value of 100,000.
  • Digit 2 has a value of 1,000,000.

One tenth of the ten thousand place is a value of 100, hence digit 2 has a value that is 1/10 the value of the 7 in the ten thousand place.

The number 321.8 is 34% of x. What is the value of x rounded to the nearest whole number?
Anni [7]

Answer:

946

Step-by-step explanation:

Let's make an equation :

34% of x = 321.8

Covert 34% into decimal by dividing by 100 :

34 ÷ 100 = 0.34

Rewrite equation with decimal form :

0.34x = 321.8

Divide both sides by x to make x the subject :

x = 321.8 ÷0.34

x = 946.470588235

To the nearest whole number will be 946 as 4 rounds it down

So our final answer will be 946

Hope this helped and have a good day
