Learn on PengiEureka Math, Grade 5Chapter 13: Partial Quotients and Multi-Digit Decimal Division

Lesson 4: Divide decimal dividends by two-digit divisors, estimating quotients, reasoning about the placement of the decimal point, and making connections to a written method.

Grade 5 students in Eureka Math Chapter 13 learn to divide decimal dividends by two-digit divisors, practicing how to estimate quotients and reason about decimal point placement using the standard algorithm. Through problems like dividing 77 kilometers equally among 22 runners or splitting 14.7 mL of serum into 21 containers, students connect estimation strategies to a written division method. This lesson builds fluency with multi-digit decimal division while reinforcing unit conversions and real-world problem solving.

Section 1

Dividing Decimals by Two-Digit Divisors

Property

To divide a decimal by a whole number using the standard algorithm, place the decimal point in the quotient directly above the decimal point in the dividend.
Then, divide as you would with whole numbers.
