The placement of the decimal point is 0.081

Further explanation

If 7.29 9 0.81, then the quotient of 7.29 90 is explain the placement of the decimal point. Use place value reasoning

A quotient is the quantity produced by the division of two numbers. The quotient is commonly referred to as a fraction or a ratio.

Decimal numbers, such as 0.6495, have four digits after the decimal point. Each digit is a different place value. The first digit after the decimal point is called the tenths place value.

Place value is the value of where a digit is in the number. For example in 352, the 5 is in the "tens" place, so its place value is 10.

Given that

[tex]\frac{ 7.29}{9} = 0.81[/tex]

Then we have to find [tex]\frac{ 7.29}{90}[/tex]

We know that

[tex]\frac{1}{10} = 0.1[/tex]

[tex]\frac{1}{100} = 0.01[/tex]

So

Here digits are same, only 9 is replace by 90.

So we can say that

[tex]\frac{7.29}{90} = 0.081[/tex]
