Answer 1

Step-by-step explanation:

1 yes there is negative integer

Answer 2

Step-by-step explanation:

1. When one positive and one negative integers are added, we take their difference and place the sign of the bigger integer. The bigger integer is decided by ignoring the signs of both the integers. For example: (– 56) + (73) = 17.

2. -10

3. When subtracting fractions from whole numbers, change the whole number into a fraction, then form a common denominator and subtract the two numerators.

4. Any number can be converted to fraction if you use 1 as the denominator:

21

1

So now that we've converted 21 into a fraction, to work out the answer, we put the fraction 1/3 side by side with our new fraction, 21/1 so that we can multiply those two fractions.

That's right, all you need to do is convert the whole number to a fraction and then multiply the numerators and denominators. Let's take a look:

1 x 21

3 x 1

=

21

3

In this case, our new fraction can actually be simplified down further. To do that, we need to find the greatest common factor of both numbers.

You can use our handy GCF calculator to work this out yourself if you want to. We already did that, and the GCF of 21 and 3 is 3.

We can now divide both the new numerator and the denominator by 3 to simplify this fraction down to its lowest terms.

21/3 = 7

3/3 = 1

When we put that together, we can see that our complete answer is:

7

1

The complete and simplified answer to the question what is 1/3 of 21 is:7

5. 77 rupees 7 paise is equal to Rs. 77. 07.

6. 105 is greater than 10.5
