Question

Is finding 9/8, subtracted by 1/2 the same as finding 9/10 subtracted by 1/4 subtracted by 1/4 ? explain .

Answer 1

Let's evaluate each expression separately and see if they are equal:

9/8 - 1/2

To subtract two fractions, we need to have a common denominator. The common denominator of 8 and 2 is 8. We can rewrite 1/2 as 4/8:

9/8 - 4/8 = 5/8

Now let's evaluate the second expression:

9/10 - 1/4 - 1/4

To subtract 1/4 from 9/10, we need a common denominator of 4 x 10 = 40:

9/10 - 10/40 - 10/40 = 18/20 - 10/40 - 10/40 = 18/20 - 1/4 - 1/4 = 9/10 - 1/2

So, the two expressions are equal:

9/8 - 1/2 = 9/10 - 1/4 - 1/4
