The answers are X = 60
Y = 119
As you can see from what I’ve drawn, 12 divided by -2 will give us -6 (12/-2=-6).
Now, ask yourself this:
3 multiplied by what makes - 6? (You have to divide) so, - 6/3= - 2. The answer is 2. So one number must be 2.
Now, what times what makes 2? 1 x 2. Since we already have 2, we just have to add 1. So the last number will be 1.
<h2>Решение (а):</h2>
Чтобы найти значение x, воспользуемся перекрестным умножением.
Что значит ,
= 2 × 30 = 5 × х
= 2 × 30 = 5x
= 60 = 5x
= х = 60 ÷ 5
= х = 12
Следовательно, 2/5 = 12/30.
<h2> Решение (б):</h2>
Чтобы найти значение x, воспользуемся перекрестным умножением.
Что значит ,
= 30 × 8 = 48 × х
= 30 × 8 = 48x
= 240 = 48x
= х = 240 ÷ 48
= х = 5
Следовательно, 5/8 = 30/48 .
There is a difference of +3 between each number, so your following number would be 21+3 = 24
