Question

evaluate 3 by 7 plus minus 4 by 9 minus minus 11 by 7 minus 7 by 9​

Answer 1

Answer:

3/7 + -4/9 - -11/7 - 7/9

First, make all the denominators equal by finding LCM

LCM of 7,9 = 63.

Next, multiply all the fractions by the number required to make their denominator equal

3/7 = 27/63

-4/9= -28/63

-11/7= -99/63

7/9= 49/63

now, apply the operations

27/63 + (-28/63) - (-99/63) - 49/63

= 27/63 - 28/63 +99/63 - 49/63

= -1/63 +99/63 -49/63

= 98/63 - 49/63

= 49/63

Reduce to lowest form:

= 7/9
