fraction worksheet

This week in maths. My group had to do a worksheet about fractions I thought it was hard but it was easy. We had to convert a mixed fraction into a improper fraction  for example 4 3/5 we had to times the denominator with the whole number and then add the numerator like this 4 x 5 + 3 = 23 so the answer is 23/5 because the 5 came from the denominator so that's your answer.
