The tenths digit of a two-digit number is 3 more than the units' digit. The number is 8 more than six times the sum of the digits. Find the number.?
74
Let a1 represent the tens digit and ao represent the unit digit. From the problem, we have two equations:
10a1+ao = 8+6(a1+ao)
a1=3+ao
Substitute a1from the second equation into the first equation and solve for a0:
10(3+ao)+ao = 8+6((3+ao)+ao)
30+10ao+ao = 8+18+6ao+6ao
30+11ao = 26+12ao
a0=4
Substituting this back into the second equation, we get:
a1=3+4=7

How many tenths are in the number 54.724?
There are five tenths in the number 54.724. To find this, you look at the digit in the tenths place, which is 7. This digit represents seven tenths. The digits to the right of the tenths place do not contribute to the number of tenths.
How does the value of a decimal change as you move to the left or the right in a place value chart?
As the digits are moved left, the digit in the tenths column goes into the units column, the digit in the hundredths column goes into the tenths column, etc; each digit is ten times its previous value, thus moving the digits to the left multiplies the number by 10. Similarly moving the digits to the right: the digit in the units column goes into the tenths column, the digit in the tenths column goes into the hundredths column, etc; each digit is a tenth of its previous value, thus moving the digits to the right divides the number by 10.
What is the name of a number that has a digit in the tenths place hundredths place and beyond?

Is 4.1 or 4.11 greater?
To determine which number is greater, we can compare the digits place by place starting from the left. In this case, the first digit after the decimal point is the tenths place. In 4.1, the digit in the tenths place is 1, and in 4.11, the digit in the tenths place is also 1. Since these digits are the same, we then compare the next digit after the tenths place, which is the hundredths place. In 4.1, the hundredths place is 0, and in 4.11, the hundredths place is 1. Therefore, 4.11 is greater than 4.1.
What is the difference between a decimal point and a decimal place?
The decimal point of a number separates the whole part of the number from the fractional part of the number. It is located between the units column and the tenths column of every number. A decimal place is one of the digits after the decimal point: The first decimal place is the first digit, which is the tenths digit The second decimal place is the second digit, which is the hundredths digit The third decimal place is the third digit, which is the thousandths digit etc. When showing or rounding to a number of decimal places there will be that number of digits after the decimal place. eg the number 5.671 has three decimal places as there are three digits after the decimal point and the second decimal place, for example, contains the digit 7.
