Answer 1

Explicación paso a paso:

1)

2/3 = 4/x

2(x) = 3(4)

2x = 12

x = 12/2

x = 6

2)

x/12 = 8/48

x(48) = 8(12)

48x = 96

x = 96/48

x = 2

3)

5/x = 15/18

5(18) = 15(x)

90 = 15x

90/15 = x

6 = x

4)

6/3 = 4/x

6(x) = 4(3)

6x = 12

x = 12/6

x = 2

5)

12/9 = x/63

12(63) = 9(x)

756 = 9x

756/9 = x

84 = x
