Question

Select all equations that are true. A. 3/4 - 1/2 = 1/4B. 9/16 - 4/8 = 5/8C. 7/8 - 3/4 = 1/8D. 7/15 - 1/3 = 6/15E. 1/2 - 1/20 = 10/20

Answer 1

A. 3/4 - 1/2 = 1/4

C. 7/8 - 3/4 = 1/8

Step-by-step explanation:

To determine the equations that are true, evaluate each of them.

`\begin{gathered} (3)/(4)-(1)/(2)=(3-2)/(4)=(1)/(4) \\ (9)/(16)-(4)/(8)=(9-8)/(16)=(1)/(16)\\eq(5)/(8) \end{gathered}`

Continuing in like manner:

`\begin{gathered} (7)/(8)-(3)/(4)=(7-6)/(8)=(1)/(8) \\ (7)/(15)-(1)/(3)=(7-5)/(15)=(2)/(15)\\eq(6)/(15) \\ (1)/(2)-(1)/(20)=(10-1)/(20)=(9)/(20)\\eq(10)/(20) \end{gathered}`

Therefore, options A and C are true.
