Divide:
a) 250 CZK in the ratio 2:3
b) 1000 CZK in the ratio 4:7:9

Correct answer:

a₁ =  100
a₂ =  150
b₁ =  200
b₂ =  350
b₃ =  450

Step-by-step explanation:

$a_1=250\cdot 2\mathrm{/}(2+3)=100$

$a_2=250\cdot 3\mathrm{/}(2+3)=150$

$b_1=1000\cdot 4\mathrm{/}(4+7+9)=200$

$b_2=1000\cdot 7\mathrm{/}(4+7+9)=350$

$b_3=1000\cdot 9\mathrm{/}(4+7+9)=450$
