Easy way of adding 44 and 48.

- Subtract 48 - 44
- Add 48 - 44
- Add 0
- Add 50 + 42

Hint:

### Adding two or more numbers results in the total sum of those values combined. And when two equal number of opposite signs are added the result is 0.

## The correct answer is: Add 50 + 42

### Here, we have to find the easy way of adding 44 and 48.

Now, 48 + 44 = ( 50 - 2 ) + ( 42 + 2 )

= 50 + 42 + 2 - 2

= 50 + 42

Hence, the correct option is d

### Remo drove his motorcycle 325 miles on Friday, 119 miles on Saturday and 465 miles on Sunday. The best estimate of the number of miles he drove over the 3 days is_______.

We can also add all the 3 distance at first and then use front end estimation.

Here, 325 + 119 + 465 = 909 which when rounded off to nearest hundred gives 900.

### Estimate the difference between 9438 – 4519 to nearest hundred, and check the reasonableness.

Step 1 : Round Off ;

if last 2 digits are more than or equal to 50, round off to nearest hundred greater than number .

if last 2 digits are less than 50, round off to nearest hundred smaller than number.

9438 rounds off to 9400.

4519 rounds off to 4500.

Step 2 : Perform Subtraction

9400 - 4500 = 4900

4900 is very close to actual result with a difference of about 1% so it is, reasonable.

### The difference of 516 and 140 using front-end estimation is ________.

Step 1 :

In 516, five is the first number and in 140, 1 is first number or front number so simply add them.

5 - 1 = 4 as they are at hundredth place so 400

next , 16 to nearest hundred is 0 and 40 to nearest 100 is 0 .

0 - 0 = 0 ;

Step 2 :

add all estimations 400 + 0 ;

So , 400 is our final answer.
