  • ( 145,350,000 / 153,000,000 ) * 100 = 95% are working <-------- answer

    ( 143,220,000 / 154,000,000 ) * 100 = 93% are working <-------- answer

  • 145,350,000 dived by (/) 153,000,000= 0.95 so 95% do the same for the next one smaller divide by bigger. its should be about 92% or 93% something like that

  • 145,350 / 153,000 then x 100 = 95% [forget the last three zeros as they are in both numbers it makes no difference to the answer]

    Now you can do the second one
