Grade 4 · Number
Fractions, Decimals, and Their Operations
Decimals to hundredths are the natural extension of the place value system to the right of the ones position. Tenths are like the tens of the decimal world: 0.4 is four tenths, or 4/10. Hundredths are like ones: 0.07 is seven hundredths, or 7/100. The connection between fractions and decimals is not a coincidence: decimals ARE fractions with denominators that are powers of 10. Students who understand this connection can move fluidly between the two representations.
