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?
It was the easiest out of them. First I done .68x10 to make it to 6.8. I times that by 4 and made 27.2 which equaled 40 pickets.
.68x10=6.8
6.8x4=
6x4=24
8x4=3.2 27.2=40
3.4=5 27.2+3.4=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?
He will need 7 with 4.4m left on 1.
The timber is $3.55/m. How much will he have spent? He will have spent 24.85.
.05x7=.35 .5x7=3.85
3x7=21+3.85=24.85.
