Answer: 5/7
Step-by-step explanation: When dividing by a fraction, we can change the division sign to multiplication and flip the second fraction.
So 1/7 ÷ 2/10 means the same thing as 1/7 × 10/2.
So when dividing by a fraction, we can just multiply
by the reciprocal of that fraction or that fraction flipped.
Now multiply across the numerators and denominators to get 10/14.
Notice that 10/14 can be reduced to 5/7.
