b) a cincea parte din: 10;5;35;20;40.

Answer 1

a)20:4=5
40:4=10
32:4=8
24:4=6
16:4=4

b)10:5=2
5:5=1
35:5=7
20:5=4
40:5=8

Answer 2

$a) \frac{1}{4} \times 20 = \frac{20}{4} = 5$

$\frac{1}{4} \times 40 = \frac{40}{4} = 10$

$\frac{1}{4} \times 32 = \frac{32}{4} = 8$

$\frac{1}{4} \times 24 = \frac{24}{4} = 6$

$\frac{1}{4} \times 16 = \frac{16}{4} = 4$

$b) \frac{1}{5} \times 10 = \frac{10}{5} = 2$

$\frac{1}{5} \times 5 = \frac{5}{5} = 1$

$\frac{1}{5} \times 35 = \frac{35}{5} = 7$

$\frac{1}{5} \times 20 = \frac{20}{5} = 4$

$\frac{1}{5} \times 40 = \frac{40}{5} = 8$
