Question

1)75:(2х)=15:25; 2)44:99=4:(3х);

Answer 1

Ответ:

62,5 и 3

Пошаговое объяснение:

1) 75÷2x = 15÷25

2x = 75×25÷15

2x = 125

x = 62,5

2) 44÷99 = 4÷3x

3x = 99×4÷44

3x = 9

x = 3

Answer 2

It looks like you've provided two sets of equations. Let's solve them step by step:

1. $\frac{75}{2x} = \frac{15}{25}$

First, simplify the right side of the equation: $\frac{15}{25} = \frac{3}{5}$

Now, the equation becomes: $\frac{75}{2x} = \frac{3}{5}$

To solve for $x$, you can cross-multiply: $75 \cdot 5 = 2x \cdot 3$ $375 = 6x$

Now, isolate $x$: $x = \frac{375}{6}$ $x = 62.5$

2. $\frac{44}{99} = \frac{4}{3x}$

Cross-multiply again: $44 \cdot 3x = 4 \cdot 99$ $132x = 396$

Now, isolate $x$: $x = \frac{396}{132}$ $x = 3$

So, the solutions are:

1. $x = 62.5$
2. $x = 3$
