Find the difference of 3/4 and 1/28.

3/4 = 21/28 after multiplying top and bottom of 3/4 by the value 7

3*7 = 21 and 4*7 = 28

The goal is to get 3/4 into an equivalent fraction that has 28 as the denominator.

So 3/4 - 1/28 is the same as 21/28 - 1/28

The denominators are the same. We subtract the numerators to get 21-1 = 20. The denominators stay the same at 28

We have

21/28 - 1/28 = (21-1)/28 = 20/28

Now reduce 20/28 as much as possible. Divide both parts by the GCF 4

20/4 = 5

28/4 = 7

The final answer is 5/7

answer: a

step-by-step explanation: the answer is a due to the rule of symmetry; that a line of symmetry must divide a figure into 2 pieces that are the exact same, only reflected over a line of symmetry. b and c do not have lines of symmetry and would not divide the figure evenly, thus making the answer a.
