WALHT identify HCF/LCF

I have learnt how to identify high common factor and low common factor.

For Example the highest common factor of 30

1 x 30=30,  15 x 2=30,  3 x 10=30  Ten x three is the highest equation there for ten is the highest common factor.

For Example the lowest common factor of 55

Are 1, 11, 5   1 x 55=55,  5 x 11=55,  11 x 5=55  Is 1 cause it’s the lowest common factor number of 55.

Low common factors are the lowest with the number that you have.

Central interceptor report

Hello everyone and welcome to my blog.

Today everybody

The Central Interceptor is a tunnel that takes waste water to the Mangere Sewage Plant,

In Central Auckland is a drill called Hiwa-i-te-rangi, It is 190 meters long, 1 giraffe high and 4 rhinos wide. There are specialists running the drill from Italy.

The drilling process will take 5 years to complete all the tunnels. Currently the S/W and used waste mix and end up polluting the ocean. The tunnels use gravity to take used water from homes and schools, and businesses to M/S/P in order to protect our oceans. The tunnel will cost $1.2 Billion, and be 14.7km long.we hope the project will last 100 year. 

 

 

 

Creating graphs.

This week in Kowhai we have been learning how to interpret data from graphs we have made. First we gathered information and noted it in our books. We practiced creating a bar graph, pie chart, and a tally chart.

When we put the information into google sheets we did a quick test to gather a range of numbers. This was put into sheets in a column and we created a scatter graph.
What I found challenging was making the pie chart on my math’s book.
what I found easy was making the bar graph.
Thanks for reading my blog.
