Fraction of the day  

6 people from this class wrote down (before the break) that they were going to visit a foreign country. 

(There are 20 students in this class)

State what fraction of students visited a foreign country. 

State what fraction of students visited a foreign country.

Fractions as division

Numerator

Denominator

Fractions as division

120 ÷ 4

​4​​120​​

​4​​120​​

Numerator

Denominator

​2⋅4​​105−15​​

​2⋅4​​105−25​​=

Fractions as division

(105-15)÷ (2⋅4)

​2⋅4​​105−15​​

Evaluate the Numerator and Denominator first, then do division!

Fractions bingo!

When I call out a fraction, you colour the called part in a circle.

 

Make sure the colored part is EXACTLY what I called out.
