382 3/10 - 191 87/100=math difficulties please answer this question
Answers
first you need to find a common denominator , which is 100 . so multiply 3/10 by 10 with both the numerator and denominator. So your new equation should be 382 30/100 - 191 87/100. Even though 382 is larger than 191 , 3/100 is still less than 87/100. So what i do is cross out the first/whole number and then add the denominator. so i change it to look like this....
381 130/100 - 191 87/100
this way its still the same fraction but it will be easier to subtract
so first subtract 381 and 191 which equals 190 then subtract the fractions 130/100 - 87/100 which equals 47/100
