Tenths: Grandma Bea's Cookie Trays

Welcome back to Millie’s Kitchen! Grandma Bea bakes her cookies in rows of 10, so every cookie is one tenth of the row. Tenths can be written as fractions, like 3/10, or as decimals, like 0.3.

Remember: 3/10 = 0.3, which you say as “zero point three” or “three tenths”. The first place after the decimal point is the tenths place, and 10 tenths make 1 whole: 10/10 = 1.0.

Magic trick: The point means “tenths are next”: the digit right after it tells you how many tenths. 0.7 is 7 tenths, so 0.7 = 7/10.
