5 2/3× 1/5=

7/8÷ 3/5=

4/2÷9/10=​

Answer 1

Respuesta:

a.

$\frac{3}{2} + \frac{4}{3} = \frac{9 + 8}{6} = \frac{17}{6}$

b.

$\frac{7}{8} + \frac{9}{8} = \frac{7 + 9}{8} = \frac{16}{8} = \frac{2}{1} = 2$

c.

$\frac{3}{4} - \frac{1}{2} = \frac{3 - 2}{4} = \frac{1}{4}$

d.

$2 \frac{1}{5} - 1 \frac{1}{4} = \frac{1}{5} - \frac{1}{4} = \frac{4 - 5}{20} = \frac{ - 1}{20}$

e.

$5 \frac{2}{3} \times \frac{1}{5} = \frac{17}{3} \times \frac{1}{5} = \frac{102}{15} = \frac{34}{5} = 6 \frac{4}{5}$

102/3=34

15/3=5

f.

$\frac{7}{8} \div \frac{3}{5} = \frac{35}{24}$

7*5=35

8*3=24

g.

$\frac{4}{2} \div \frac{9}{10} = \frac{40}{18} = \frac{20}{9}$

40/2=20

18/2=9
