📏 Tenths, Hundredths, and Thousandths

What you’ll learn

1. TenthsUnderstand tenths as one of ten equal parts, written 1/10 or 0.1, and read the first decimal place.The first way to split a whole is into ten equal parts called tenths. One tenth is the fraction 1/10 and the decimal 0.1. The first digit after the decimal point always shows tenths, so the 7 in 0.7 means seven tenths. On a number line, the tenths sit evenly between 0 and 1.
2. HundredthsUnderstand hundredths as the second decimal place and that ten hundredths make one tenth.Splitting each tenth into ten gives a hundred tiny parts called hundredths. One hundredth is 1/100 or 0.01, and it lives in the second place after the decimal point. Ten hundredths bundle up to make one tenth, exactly like ten ones make a ten.
3. ThousandthsUnderstand thousandths as the third decimal place and read three-place decimals by their place values.Splitting a hundredth into ten reaches thousandths — a whole cut into a thousand equal parts, written 1/1000 or 0.001. It sits in the third decimal place. Read a decimal like 0.375 place by place: 3 tenths, 7 hundredths, 5 thousandths. Each place is ten times smaller than the one before.
