Which is the expanded form of the decimal (4.73)?
Answer and explanation
Correct answer: \(4+\frac{7}{10}+\frac{3}{100}\)
In 4.73, 4 is in the ones place, 7 is in the tenths place, and 3 is in the hundredths place. Therefore, its expanded form is \(4+\frac{7}{10}+\frac{3}{100}\). In option B, the place values of 7 and 3 are interchanged. Exam tip: the first digit after the decimal has denominator 10, and the second has denominator 100.
