Question

Write a fraction that is equivalent to 7/10 = _ /_

Answer 1

A fraction that is equivalent to $\frac{a}{b}$ will have the form $\frac{a\times A}{b\times B}$, where A and B are equivalent and factors that are multiplied in.
The product fraction should be easily simplified using A and B to get the original fraction.

In the case of your fraction $\frac{7}{10}$ you will need to find a fraction which is a product of this: $\frac{7\timesA}{10\timesB},A=B$
