Rewrite the given instructions in QBASIC:

1. The product of p, q and r is divided by 100.
2. m raised to the power 2 plus n raised to the power 3.
3. The sum of a and b is divided by the product of a and b.
4. Subtract 5 from m and the result is multiplied by 10.
5. The sum of p and q is multiplied by 2.
6. A is greater than or equal to B.
7. The sum of A and B is less than the product of A and B.
8. Twice the product of A plus thrice the product of B is greater than or equal to 50.

1. (p * q * r) / 100
2. m ^ 2 + n ^ 3
3. (a + b) / (a * b)
4. (m - 5) * 10
5. (p + q) * 2
6. A >= B
7. (A + B) < (A * B)
8. (2 * a + 3 * b) >= 50
