Question

1. 1/2+1/9
2.10/13-19/3
3.1/14*,8/7

Answer 1

Answer:

Here is your Answer

Step-by-step explanation:

1.

=1/2+1/9

=1×9/2×9+1×2/9×2

=9/18+2/18

=11/18

2.

=10/13-19/3

=10×3/13×3-19×13/3×13

=30/39-247/39

=247/39-30/39

=217/39

3.

=1/14×8/7

=7/112

Answer 2

1. 1/2+1/9
First we have to bring the denominators the same...
So,
=1x9/2x9 + 1x2/9x2
=9/18+2/18
=11/18
There’s also a shortcut trick for this question.
1/2+1/9
You multiply,
=1x9 + 1x2
=9+2
=11
So 11 is the numerator.
To get the denominator we just multiply the denominators.
So,
11/2x9
11/18

2.10/13-19/3
First we have to bring the denominators the same....
So,
=10x3/13x3 - 19x13/3x13
=30/39-247/39
= -217/39

3.1/14*8/7
Here we don’t need to bring them to the same denominator....We just multiply the numerator with numerator and denominator with denominator...
So,
=1/14*8/7
=8/98
Simplified form=4/49
