Ответ:

115÷5=46÷2

87÷3 =290÷10

95÷19=55÷11

208÷52=28÷7​​

Пошаговое объяснение:

1)\frac{115}{x} = \frac{46}{2} -> x = \frac{115 * 2 }{46} =   \frac{115}{23} = 5

2)\frac{87}{3} = \frac{x}{10} -> x = \frac{87 * 10}{3} = 29 * 10 = 290

3)\frac{x}{19}  = \frac{55}{11} -> x = \frac{19 * 55}{11} = 19  * 5= 95

4)\frac{208}{x} = \frac{28}{7} -> x = \frac{208 * 7}{28} = \frac{208}{4} = 52
