-(336)

## Problem 441

Add

**Solution**

We can write it as

When we multiply a negative value with a positive value then answer will be a negative value

Now take LCM which is 20

=

=

## Problem 440

Add

**Solution**

First take LCM which is 6

=

## Problem 438

Multiple (4)(-3)

**Solution**

We can see that 3 cancel out now it will become

4(-1)*7

= -28

## Problem 437

We can write is as

9 cancel out

= -2

## Problem 436

Divide

**Solution:-**

We can write it as

-3 cancel out

= 5

## Problem 435

Subtract

**Solution:-**

We can write it as

–

When we multiply a negative value by a negative sign then it become positive

Now take LCM which is 18

=

=

=
