1.75 x 1.75=blank can you explain plz

1.75 * 175 = 3.0625  

Step-by-step explanation:

In this question we have to multiply the two given values simply. First we need to  write it vertically then multiply upper side with the first number that is downside. The next step is to multiply the second number later that with the third number and at the end we will add them. In this step we will count how many numbers are there after decimal in order to put it in decimal.

Calculation;    

1.75 = 2 numbers after decimal  

1.75 = 2 numbers after decimal  

- 875  

- 2250  

- 17500  

- 3.0625

hence 4 numbers after decimal.
