Question

7 Calcule mentalmente as divisões.
600 = 3 =
5400 =9=
72000 : 8 =
600 = 30 =
5 400 - 90 =
72000 - 80 =
600 = 300 =
5400 = 900 =
72000 - 800 =​

Answer 1

Resposta:

$600 : 3 =200 \\5400 : 9=600\\72000 : 8 = 9000\\600 : 30 =20\\5 400 : 90 = 60\\72000 : 80 = 900\\600 : 300 =2\\5400 : 900 =6\\72000 : 800= 90$

Answer 2

Resposta:

$\Large \: 600 \div 3 = \boxed{ \green{ \bf \: 200}} \\ \\ \Large \: 5400 \div 9 = \boxed{ \green{ \bf \: 600}}$

$\Large \: 72000 \div 8 = \boxed{ \green{ \bf 9000}} \\ \\ \Large 600 \div 30 = \Large \boxed{ \green{ \bf 20}}$

$\Large \: 5400 \div 90 = \boxed{ \green{ \bf \: 60}}$

$\Large \: 72000 \div 80 = \boxed{ \green{ \bf \: 900}} \\ \\ \Large \: 600 \div 300 = \boxed{ \green{ \bf \:2 }}$

$\Large \: 5400 \times 900 = \boxed{ \green{ \bf 6 }}\\ \\ \Large 72000 \div 800 = \boxed{ \green{ \bf \:90 }} \\ \\ \Large \boxed{ \underline{ \blue{ \bf \: Bons \: Estudos!} \:\bf 20/05/2021}}$
