Question

find 4 rational no between -3/7 & 2/5?

Answer 1

first make the denom. same ,for this we have to multiply num. and denom. (3/7)by 5 ,and multiply num and deno. (2/5) by7 =3×5/7×5,2×7/5×7=15/35,14/35 then we have to again multiply noth num.and denom. by 5=15×5/35×5,14×5/35×5=75/175,70/175 then rational no. bw3/7 and 2/5 are 71/175,72/175,73/175,74/175
