First convert all fractions into improper fractions: 11/412/7 Then break down the nominator and denominators into their lowest common denominators (1134)/(47) Cancel the common factors on the nominator and denominator (i.e numbers that feature both on the top and bottom) (11*3)/7=33/7 To convert the fraction back into a mixed number work out how many times 7 goes into 33, which is 4 with a remainder of 5. Therefore the final answer is 4 and 5/7.
