Answer:

1. 30% of n is 1.8

We can start by setting up an equation:

0.3n = 1.8

Solving for n, we get:

n = 6

Therefore, 30% of 6 is 1.8.

2. 240 of n% is 400

We can start by setting up an equation:

(240/100)n = 400

Simplifying, we get:

2.4n = 400

Solving for n, we get:

n = 166.67

Therefore, 240% of 166.67 is 400.

3. 2.4 is 30% of n

We can start by setting up an equation:

0.3n = 2.4

Solving for n, we get:

n = 8

Therefore, 2.4 is 30% of 8.

4. 225 is 25% of n

We can start by setting up an equation:

0.25n = 225

Solving for n, we get:

n = 900

Therefore, 225 is 25% of 900.

5. 70% of n is 14.7

We can start by setting up an equation:

0.7n = 14.7

Solving for n, we get:

n = 21

Therefore, 70% of 21 is 14.7.

6. 113 is 13% of n

We can start by setting up an equation:

0.13n = 113

Solving for n, we get:

n = 869.23

Therefore, 113 is 13% of 869.23.

7. 28% of n is 196

We can start by setting up an equation:

0.28n = 196

Solving for n, we get:

n = 700

Therefore, 28% of 700 is 196.

8. 35% of n is 1200

We can start by setting up an equation:

0.35n = 1200

Solving for n, we get:

n = 3428.57

Therefore, 35% of 3428.57 is 1200.

9. 175.5 is 11% of n

We can start by setting up an equation:

0.11n = 175.5

Solving for n, we get:

n = 1595.45

Therefore, 175.5 is 11% of 1595.45.

10. n is 40% of 65

We can start by setting up an equation:

0.4(65) = n

Solving for n, we get:

n = 26

Therefore, 26 is 40% of 65.
