A, B and D are already rational numbers, 0.4 itself is a rational number, two rational numbers make a product of rational number.
So A, B, D are the correct choices.
Are you sure it asks for rational numbers, not irrational number?
The answer is 60 because you have to divide 7 1/2 by 1/8
The number can be separated into 35+0.125
0.125 can be rewritten as,
![\frac{125}{1000}](https://tex.z-dn.net/?f=%20%5Cfrac%7B125%7D%7B1000%7D%20)
So, the number can be rewritten;
35+
![\frac{125}{1000}](https://tex.z-dn.net/?f=%20%5Cfrac%7B125%7D%7B1000%7D%20)
35
Answer:
x = 4
Step-by-step explanation:
3 x ( 4x -7 ) = 27
3 x 4x = 12x
3 x -7 = -21
12x -21 = 27
12x -21 + 21 = 27 + 21
12x = 48
12x/12 = 48/12
x = 4
