We must follow order of operations:
1. Parentheses (there are none)
2. Exponents (none)
3. Multiply/ Divide (there is one of those, so we must divide 4/7 by 3/10.

Remember for dividing fractions:
1. ﻿Keep﻿ the original fraction
2. ﻿Change﻿ the division sign to a multiplication sign
3. ﻿Flip﻿ the last fraction
So 4/7 divided by 3/10 becomes:

When multiplying fractions, multiply straight across: numerator of the first fraction*numerator of the second fraction, denominator of the first fraction*denominator of the second fraction.

This cannot be simplified, so now we can go onto the fourth step of order of operations:
4. Add/ Subtract

However, remember that we cannot add (or subtract, for that matter,) fractions without a common denominator (the numbers on the bottom of the fraction must be the same).  To get a common denominator, multiply the fraction by a number over the same number... see it this way:

Simplify
The answer is 1.  By multiplying a fraction by a number over the same number, we are not actually changing the value of the fraction because we are, in reality, multiplying it by 1.

So back to the problem.

We can get a common denominator by multiplying 1/3 by 7/7.  This will result in the denominator being 21, the same as the denominator of the second fraction.

This is our final answer, because 47/21 cannot be simplified.
Thank you t
Can you also help me on the next question that i post too
I will, which one is it?
The one that says something about 7/8x4/5 divided by 7/20
Ok I did it
