Answer: kindly check explanation

Step-by-step explanation:

Given the following statements :

A.) To find 49 times 73. I multiply 73 times 50 and take off one group of 73

To obtain the product of (49 and 73)

(73 * 50) - 73

3650 - 73

= 3577

B.) To find 15 times 16, I double 15 and halve 16 and then multiply

Double 15 = (15 * 2) = 30

Halve 16 = (16 / 2) = 8 ;

Then multiply:

(30 * 8) = 240

Similarly ;

(15 × 2) × (16 / 2) = 240
