Practical Percentages

KPMG Trip

 On Wednesday the 23rd of June the year 7&8 extension and some other students went to KPMG. We had to bus to KPMG it took forty minutes to get there. The first thing we did was have a tour in 4 groups air, fire, water and earth I was in air. After the tour we had morning tea that was provided by KPMG it was tasty. We did experiments based on our group names. My group had to mix baking soda with vinegar and pour it in a bottle and put a balloon on it and see that the balloon started to full up with carbon dioxide. We did a quiz about the environments of the world and the winners got a prize. It was a fun time at KPMG it was a good experience.

We are learning to add and subtract up to three decimal places. We are learning to convert between fractions, decimals and percentages.

What is 244/1000 as a decimal?

0.0244

What is 55/100 as decimal?

.55

What is 12/1000 as a decimal? 

0.0012

What is ½ as a decimal?

0.5

What is ¼ as a decimal?

0.25

What is ⅕  as a decimal?

0.2

What is ⅛ as a decimal?

0.125

0.45 + 0.42 = 0.87

0.56 + 0.17 = 0.73

0.67 + 0.91 = 1.58

0.555 + 0.014 = 0.569

0.7 - 0.45 = 0.35

0.55 - 0.45 = 0.1

0.76 - 0.29 = 0.47

2.5 - 0.78 = 1.72

1.7 - 0.999 = 0.611

0.934 - 0. 244= 0.790

0.944 - 0. 119 = 0.825

50/100 = 50%?

1/10 = 10% ?

0.4 = 40%?

0.05 = 5%?

0.9 = 90%?
