Detailed Solution

Concept-When we write a number in its expanded form, we use addition, multiplication, and division to write the terms. Take the supplied number and expand it using the available options.
Pick the indicated number: 2.06
Expanding the above number yields -2.06 = 2+0.06
Make use of the multiplicative identity, which says that any number "a" multiplied by it yields the value of the original number.
2.06=(2×1)
+0.06
Decimal point conversion to fraction form. Place the decimal number above its place value to convert it to a fraction. If there are two digits after the decimal point, for instance, 0.06, the six is in the hundredths place so we place 6 over 100 to create the equivalent fraction, which is pick the indicated number: 2.06
Expanding the above number yields -2.06 = 2 + 0.06
Make use of the multiplicative identity, which says that any number "a" multiplied by it yields the value of the original number.
2.06  = 2×1)
+0.06
Decimal point conversion to fraction form. Place the decimal number above its place value to convert it to a fraction. If there are two digits after the decimal point, for instance, 0.06, the six is in the hundredths place so we place 6 over 100 to create the equivalent fraction, which is 6100.  Likewise, if there are only one or two digits after the decimal point, 0.06, the six is in the tenths place so we place 6 over 10 to create the equivalent fraction, which is610.
Therefore, the statement above can be written as 2.06=(2×1)+. (6100)
A fraction is a number that is stated as a ratio of numerator to denominator. You might also write it as division. In this case, 6100 can be written as 6100 =2.06 = (2×1)+(6100)
Hence, the correct option is 4.
