**3. Tiaki is fixing part of his fence. The pickets he needs are .68m long each. How many metres of timber does he need to cut up 45 pickets? answer: 30.6m**

**0.68 x 20 = 13.6**

**0.68 x 20 = 13.6**

**0.68 x 5 = 3.4**

**Add altogether equals 30.6**

If the timber comes in 5m lengths only what is the minimum amount of lengths he needs to have enough for 45 pickets? answer:225

45 x 5 =225.

40 x 5 = 200

5 x 5 = 25

200 + 25 = 225

The timber is $3.55/m. How much will he have spent? answer: $106.50.

30 x 3.55 = 106.5

30 x 3 = 90

30 x 0.55 = 16.5
