Question

afla necunoscute a×4=804 3×c=399 500÷a=5 777÷e=7 d÷9=50 2×b=824​

Answer 1

Răspuns:

4a = 804

a = 201

3c = 399

c = 133

$\frac{500}{a} = \frac{5}{1}$

$a = \frac{500}{5}$

$a = 100$

$\frac{777}{e} = \frac{7}{1}$

$e = \frac{777}{7}$

$e = 111$

$\frac{d}{9} = \frac{50}{1}$

$d = 9 \times 50$

$d = 450$

2b = 824

b = 412
