  Well I just need some help with these quesions please?
  
  1. Find out the product of 12 and 62. Then round off your answer to the nearest ten.
  
  2. 140 x ___ = 42.
  
  3. Express 64% as a fraction in its simplest form.
  
  4. Express 200g as a percentage of 4kg.
  
  Note: If you know some of the questions, just tell me but dont tell me what is the answer, just tell me the working would do.

  1. 12 × 62 = 744. Round off = 740.
  2. 140/42 = 10/3
  3. 64% = 64/100 = 16/25
  4. 200g/4000g = 1/20
  
  It is impossible to show working, very straight-forward.

  1. Find out the product of 12 and 62. Then round off your answer to the nearest ten.
  
  multiply them and... round them off?
  
  sort of if it's 42, then the nearest ten is 40.. if it's 46, then nearest ten is 50
  
  2. 140 x ___ = 42.
  
  140 x A = A x 140..
  therefore.. divide both sides by 140 to get the answer
  
  3. Express 64% as a fraction in its simplest form.
  
  64% = 64/100
  divide top and bottom by common integer factors until you get both numerator and denominator which do not have common integer factors
  
  4. Express 200g as a percentage of 4kg.
  
  1kg = 1000g
  therefore 200g/4000g x 100% = answer

  1. 12x62= answer.xx, make it into the nearest 10.
  
  2. 140 x ___ = 42 = x = 42/140
  
  3. 64% = 64/100
  
  4. 200/4000 x 100/1 =

  1. Product = multiply. 12 X 62 = _________, then round it off. Not very hard.
  
  2. 42/140
  
  3. Percentage in fraction is always expressed over 100. Therefore, 64% = 64/100. Reduce it yourself.
  
  4. Change all to grams, (small number/big number) X 100%
  
  For your info, 1kg = 1000g
  
  Go figure
