Gemma 2

Gemma works in a bakery. She is making up family boxes of bakery goods. Each box needs 3 loaves of bread—three loaves in a box.

If Gemma has 20 loaves of bread:

a) How many family boxes can she make?

b) How many loaves of bread are left over?

Correct answer:

a =  6
b =  2

Step-by-step explanation:

$$\begin{gathered} n_1=20/3=\frac{20}{3}=6\frac{2}{3}\doteq 6.6667 \\ a=\lfloor n_1\rfloor =\lfloor 6.6667\rfloor =6 \end{gathered}$$

$b=20-3\cdot a=20-3\cdot 6=2$
