Question

What expresion is the same as 10 divide 4

Answer 1

10 / 4 is a fraction, and with fractions, you can reduce or increase the numerator and denominator as long as you keep the same ratio. For instance 2/4 is the same as 1/2 because 2 is half of 4 and 1 is half of 2.  An easy way to find equivalent fractions is to divide or multiply the top and bottom by the same value. For the example I used, if I multiply 1/2 by 2/2 I get 2/4 which is equivalent. In this case you can either multiply 10/4 by something like 2/2 and get 20/8 or you can divide 10/4 by 2/2 and get 5/2.
