Cô Dung có 23 phong kẹo, mỗi phong có 10 viên kẹo. Cô chia đều số kẹo đó cho 10 bạn. Vậy mỗi bạn nhận được:

a) \(4\frac{1}{4}\,\, - \,\,2\frac{5}{8}\,\, + \,\,2\frac{3}{5}\)  

= .....................................................

= .....................................................

= .....................................................

b) \(5\frac{1}{7}\,\, - \,\,2\frac{4}{5}\,\,:\,\,1\frac{1}{5}\)

= .....................................................

= .....................................................

= .....................................................

c) \(2\frac{3}{5}\,\, + \,\,1\frac{1}{4}\,\, \times \,\,2\frac{2}{3}\)  

= .....................................................

= .....................................................

= .....................................................

d) \(4\frac{1}{3}\,\, \times \,\,1\frac{1}{2}\,\, + \,\,5\frac{2}{7}\)

= .....................................................

= .....................................................

= .....................................................

\(1\frac{4}{5}\,\, = \,\,\frac{{.......}}{{.......}}\,\, = \,\,\frac{{.......}}{{.......}}\)

\(5\frac{1}{{20}}\,\, = \,\,\frac{{.......}}{{.......}}\,\, = \,\,\frac{{.......}}{{.......}}\)

\(6\frac{7}{{10}}\,\,\, = \,\,\,\frac{{.......}}{{.......}}\,\,\, = \,\,\,\frac{{.......}}{{.......}}\)

\(3\frac{3}{{50}}\,\,\, = \,\,\,\frac{{.......}}{{.......}}\,\, = \,\,\frac{{.......}}{{.......}}\)
