you would times 8.7 and 6
If you put brackets around (2+1), your method of working is:
1) 15-4*(2+1)=3
2) 15-4*3=3
3) 15-12=3
You don't need any more brackets, as the BIDMAS (brackets, Indices, division, multiplication, addition, subtraction) rule does the rest of the job for you.
The answer is therefore: 15-4*(2+1)=3

First change the 230 grams to kilograms or 1 kilogram to grams.
The units have to be the same.
Next set up a proportion.
Cross multiply to solve the proportion.
1 kg = 1000g
230 g/30 biscuits = 1000g/x biscuits
230x = 30(1000)
230x = 30000
divide both sides by 230
x =130 biscuits
