1515 3 x =

26
1515 3 x 1.Times the denominator by the whole number =

27
Remember to convert mixed numbers to top heavy fractions 1515 3 x 1.Times the denominator by the whole number (In this case we get 5x3=15) =

28
Remember to convert mixed numbers to top heavy fractions 1515 3 + x 1.Times the denominator by the whole number (In this case we get 5x3=15) =

29
Remember to convert mixed numbers to top heavy fractions 1515 3 + x 1.Times the denominator by the whole number (In this case we get 5x3=15) 2. Add the product to the numerator =

30
Remember to convert mixed numbers to top heavy fractions 1515 3 + x 1.Times the denominator by the whole number (In this case we get 5x3=15) 2. Add the product to the numerator (So 15+1=16) =

31
Remember to convert mixed numbers to top heavy fractions 1515 3 + x 1.Times the denominator by the whole number 2. Add the product to the numerator = 3. Put this number over the existing denominator (In this case we get 5x3=15) (So 15+1=16)

32
(In this case the denominator is 5) Remember to convert mixed numbers to top heavy fractions 1515 3 + x 1.Times the denominator by the whole number 2. Add the product to the numerator = 3. Put this number over the existing denominator (In this case we get 5x3=15) (So 15+1=16)

33
Remember to convert mixed numbers to top heavy fractions 1515 3 + x 1.Times the denominator by the whole number (In this case we get 5x3=15) 2. Add the product to the numerator (So 15+1=16) = 16 5 3. Put this number over the existing denominator (In this case the denominator is 5)
