Predict the result
How can three quarters be written as a decimal?
The fraction bar tells you which operation to use.

Set up the model
A fraction means its numerator divided by its denominator.
Divide three by four.

Work the example
Three divided by four gives a terminating decimal.
The quotient is zero point seven five.
So three quarters and zero point seven five are equal.
Multiplying zero point seven five by four gives three.

Check the result
Now write one quarter as a decimal.
Take eight seconds to think before the answer appears.
[Eight-second silent pause to work; the answer remains hidden.]
One divided by four is zero point two five.
One quarter and zero point two five name the same number.

Interpret the result
Use division to compare fraction and decimal representations.
Use the original task and check that your result fits its meaning.
