Rovnice a desatinné číslaEquation and decimal numbers

Class 5C

• rozcvička - warm up

• päťminútovka - quiz

• rovnica - equation

• precvičovanie - practise

• opakovanie - revision

. 3.2 three point two

+ 5+6 five plus six

- 10-4 ten minus four

x 4x6 four multiplied by six

four times six

: 4:2 four divided by two

= 1+2= 3 one plus two equals three

Päťminútovka - Quiz

0,45 : 9=0,05

7,2 : 0,06=120

88,2 : 1,4=63

56,78 : 0,001=56780

Skupina B

0,048 : 8=0,006

4,5 :0,09=50

8,19 :0,13=63

15,59 : 0,01=1559

Kontrola päťminútovky

Kúpila čokoládku za 5,40 Sk

a 1 rožok. Spolu zaplatila 6,90 Sk. Koľko korún stál rožok?

x + 5,40 = 6,90

x = 6,90-5,40

x = 1,50

sk: Ľ: 10,2-3,2= 7

P: 7

Ľ=P

Čo je to rovnica?

Rovnica - Equation

x–3,2 = 7

x = 7 + 3,2

x = 10,2

sk:Ľ: 10,2-3,2= 7

P: 7

Ľ=P

3.x = 2,7

x = 2,7 : 3

x = 0,9

sk:Ľ: 3. 0,9=2,7

P: 2,7

Ľ=P

Precvičovanie - Practise
