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.
