1 93/1000 = 0.093

2 13/20 = 0.65

3 0.03 - 0.021 = 0.009

8 0.175 x 2507.47 = 438.81

9 14 divided by 0.007 = 2000

10 66 cents

11 14 x 87.6 = 1226.40

1.As there are 3 zeros in 1,000, go back 3 decimal places in 93.
0.093

2.When you divide by 20, you divide by 2 then 10 right?
So divide 13 by 2 =6.5
Then divide 6.5 by 10 (go back one d.p. as there is one zero) = 0.65

3.Change these into fractions. How? Firstly see how many numbers after decimal point.
0.03 has 2, so it must be 3/100 (because 100 has 2 zeros)
0.021 has 3 so it must be 21/ 1000
3/100 – 21/1000 = 30/1000 (x 10 to get same denominator) - 21/1000 = 9/1000
9/1000 = 0.009 mm (refer back to Q1 for why)


8.2507.47 x 0.175 = 438. 80725 is the calculator answer.
Rounding to a cent means rounding to the nearest 1/100 (0.01)so rounding 438.80(7) is $438.81


9.14/ 0.007 = 14 divided by 7/1000 = 14 divided by 7 multiplied by 1000. 14 divided by 7 is 2.
= 2 multiplied by 1000
= 2000

10. 6.55 divided by 10
$0.655 = $0.66 to the nearest cent.


11.1.4 x 87.6
Move forward a decimal place each for easy multiplication 14 x 876 = 12264
Then move back 2 decimal places $122.64.
