Dazzling Decimals 2

Dazzling Decimals 2
This week 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 = 0.244

What is 55/100 as decimal = 0.55

What is 12/1000 as a decimal = 0.012

What is ½ as a decimal = 0.50

What is ¼ as a decimal =  0.25

What is ⅕  as a decimal = 0.20

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 = 0.25

0.55 - 0.45 = 0.1

0.76 - 0.29 = 0.47

2.5 - 0.78 = 1.72

1.7 - 0.999 = 0.701

0.934 - 0.244 = 0.69

0.944 - 0.119 = 0.825

50/100 = 50%

1/10 = 10%

0.4 = 40%
0.05 = 5%
0.9 = 90%
