Question

1) Find 2 rational numbers between3/4 and 1/7.
2) Simplify 3/5+7/6+-2/3+-7/10.​

Answer 1

1)

3/4 &1/7 is equal to 21/28 & 4/28

therefore two rational numbers between 3/4 & 1/7 are

6/28, 8/28,10/28, 12/28 etc

that is 3/14, 2/7 ,5/14, 3/7 etc

2) 3/5+7/6+-2/3+-7/10

=3/5+7/6-(2/3+7/10)

=((3*6+5*7)/(5*6))-((2*10+3*7)/(3*10))

=((18+35)/30)-((20+21)/30)

=(53/30)-(41/30)

=(53-41)/30

=12/30

=2/5
