A Peek Beyond the Point — Class 7 Mathematics

This chapter extends the place value system below the units place to introduce decimals. To measure more precisely, a unit is split into ten one-tenths, each one-tenth into ten one-hundredths, and so on, so that and . A decimal point separates the whole-number part from the fractional part: means , while means . You learn to read numbers like as "zero point two seven four", to see that trailing zeros do not change a value , and to locate and compare decimals on the number line by comparing digits place by place.
