Find the Quotient

0.48 ÷ 2 ___(On your place value chart, draw 48 hundredths in number disks.)

Find the Quotient

0.48 ÷ 2 ___48 hundredths ÷ 2 = ___ hundredths

Find the Quotient

0.48 ÷ 2 ___48 hundredths ÷ 2 = 24 hundredths = ____ tenths ____ hundredths

Find the Quotient

0.48 ÷ 2 ___48 hundredths ÷ 2 = 24 hundredths = 2 tenths 4 hundredths Now solve using the standard algorithm

0.42 ÷ 3 ___(On your place value chart, draw 42 hundredths in number disks.)

Find the Quotient

0.42 ÷ 3 ___42 hundredths ÷ 3 = ___ hundredths

Find the Quotient

0.42 ÷ 3 ___42 hundredths ÷ 3 = 14 hundredths = ___ tenths ___ hundredths

Find the Quotient

0.42 ÷ 3 ___42 hundredths ÷ 3 = 14 hundredths = 1 tenth 4 hundredths

Find the Quotient

0.42 ÷ 3 ___42 hundredths ÷ 3 = 14 hundredths = 1 tenth 4 hundredthsNow solve using the standard algorithm.

Application Problem

Jose bought a bag of 6 oranges for $2.82. He also bought 5 pineapples. He gave the cashier $20 and received $1.43 change. What did each pineapple cost?

Application Problem

Jose bought a bag of 6 oranges for $2.82. He also bought 5 pineapples. He gave the cashier $20 and received $1.43 change. What did each pineapple cost?

$2.82 ? $1.43 = $20Oranges 5 pineapples Change

Application Problem

Jose bought a bag of 6 oranges for $2.82. He also bought 5 pineapples. He gave the cashier $20 and received $1.43 change. What did each pineapple cost?

$2.82 ? $1.43 = $20Oranges 5 pineapples Change

$20 - $2.82 - $1.43 = Pineapples

Application Problem

$2.82 ? $1.43 = $20Oranges 5 pineapples Change

$20 - $2.82 - $1.43 = $15.75

Application Problem

? ? ? ? ? = $15.75

Application Problem

? ? ? ? ? = $15.75

$15.75 ÷ 5 =

Application Problem

? ? ? ? ? = $15.75

$15.75 ÷ 5 = $3.15 for each pineapple
