    A baker uses 34\frac{3}{4} of a bag of flour for bread and 25\frac{2}{5} of a bag for cakes. How much flour does he use in total?

    The fractions need a common denominator before they can be added. The smallest one is a common multiple of 44 and 55.

    Solution

    Step 1 of 3

    1. 1.34=1520\frac{3}{4} = \frac{15}{20} and 25=820\frac{2}{5} = \frac{8}{20}
