Gideon ran  $$2\frac{4}{5}$$  miles last weekend.  This weekend he ran  $$3\frac{1}{5}$$  miles.  How many miles did he run in all?

Tell whether the number sentence is True or False.
$$10\frac{2}{5}+5\frac{1}{5}=15\frac{3}{10}$$  

$$5\ \frac{1}{4}+3\ \frac{2}{4}$$  

$$1\ \frac{2}{5}\ +\ 1\ \frac{4}{5}\ =$$  

Convert
$$3\ \frac{1}{5}$$  into an improper fraction

(a)  

$$7\ \frac{3}{5}+4\ \frac{1}{5}$$

2 $$\frac{7}{8}$$  + 4 $$\frac{5}{8}$$  =

6 $$\frac{2}{3}$$  + 3 $$\frac{2}{3}$$  =
