Question

Divide the sum of 3/4and-4/7by their difference​

Answer 1

Answer:

first we have to find the sum;

3/4+(-4/7)

=3/4-4/7

=21-16/28

=5/28

now we have to find the difference;

3/4-(-4/7)

=3/4+4/7

=21+16/28

=37/28

Now we do the divide;

5/28 divided by 37/28

=5/28*28/37

=5/37

the answer is 5/37

Answer 2

Answer:

5/37

Step-by-step explanation:

Nos. are 3/4 and -4/7

1. Sum = 3/4 + (-4/7)
2. Sum = 3/4 - 4/7............LCM OF 4 & 7 = 28
3. Sum =[ (3*7)-(4*4)]/28
4. Sum =[ 21 - 16 ] / 28
5. Sum = 5/28

1. Difference = 3/4 - (-4/7)
2. Difference = 3/4 + 4/7.................LCM OF 4 & 7 = 28
3. Difference = [(3*7)+(4*4)] / 28
4. Difference = [ 21 + 16 ] / 28
5. Difference = 37 / 28

1. Sum / Difference = 5/28 divided by 37/28
2.                               = 5/28 * 28 / 37
3.                               = 5/37
