This is a big challenge for me as I love doing maths. Anyways this task is about Fraction, Decimal and Percentage. Enjoy

Dazzling Decimals

Flash Addition!

 114 + 97 = 211

 93 + 289= 382

 128 + 87 = 215

163 + 84 = 247

 311 + 93 = 404

Change to fractions and decimals

1. 21% -  0.21  21/100

2. 19% - 0.19 19/100

3. 35% - 0.35 35/100

4. 63% 0.63 63/100

5. 40% 0.40 40/100

6. 15% 0.15 15/100

7. 75% 0.75 75/100

8. 83% 0.83 83/100

9. 7%  0.7 7/100

10. 1% 0.1 01/100

Change to percentages

½ = 50%

⅗ =  60%

17/20=

41/ 50= 82%

7/10 = 70%

⅓=   33.333333333333333333333333

⅚= 25

14/35= 40% 

1/25=  4%

5/50 = 10%

1. 35 + 97 = 132

2. 3.25 - 1.17= 2.08

3. 2 × -8 = -16

4. 5 × (2 + 4 × 3) = 70

5. 5.789 - 1.345 = 4.444

6. 1.789 - 0.987 = 0.802

7. 1.67 + 5.895 = 7.565

8. 1.578  + 2.654 = 4.322

9. 7.678 - 3.567 = 4.111

10. 4.789 + 1.678 = 6.467

This is a math based task. We learnt about Decimals & Fractions. We had to change some questions into fractions and decimals. The top addition question were really easy. Some questions were challenging but me and my group went through the questions and worked them out.

Fractions Star

Task Description: This week in maths we did fractions. We learnt about fractions, the higher level the more higher the questions get. The questions will start getting more challenging over-time.

Fractions of A Set

Task Description: Today in maths we did fractions. We have to use our multiplication facts to work out and solve mixed and improper fractions. My technique was to see how much of the denominator can go into the numerator to solve the problem.
