Answer:

25.07 × 5.4 = 135.378

Step-by-step explanation:

In placement of the decimal point in multiplication , first check the numbers that will multiply and count the individual decimal points in the numbers.

In this case,

25.07 × 5.4 = 2 * 1 -------decimal place

The answer should have  2+1 = 3 decimal places-----note the addition sign

25.07 × 5.4 = 135.378 ---------the answer has 3 decimal places

The first answer is incorrect because ;

2.52 × 27.94 = 704.088 ----2 *2 = 4 , but the answer has 3

The second answer is incorrect because;

94.1 × 2.5 = 23.525 -----1 * 1= 2 decimal places, the answer has 3

The third answer is incorrect because ;

1.83 × 2.9 = 53.07--------2*1= 3 decimal places , the answer has 2

Answer:

25.07 x 5.4 is the answer
