Question

1) 20,4 *6,5 + 3,8 * 18;e) 7,2*3,6 - 4,8*5,4.​

Answer 1

1) 132.6  + 68.4 = 201

2) 25.92 -25.92 = 0

Answer 2

To solve the expression:

1. 20.4 * 6.5 + 3.8 * 18

We perform the multiplication first:

= (20.4 * 6.5) + (3.8 * 18) = 132.6 + 68.4

Then, we add the results:

= 201

Therefore, 20.4 * 6.5 + 3.8 * 18 equals 201.

2. 7.2 * 3.6 - 4.8 * 5.4

Again, we start with the multiplication:

= (7.2 * 3.6) - (4.8 * 5.4) = 25.92 - 25.92

Then, we subtract the results:

= 0

Therefore, 7.2 * 3.6 - 4.8 * 5.4 equals 0.
