Question

what should be added to -7/20 to get 5/8 write steps

Answer 1

Answer:

39/40 should be added to -7/20 to get 5/8.

Step-by-step explanation:

first we will assume that x be added to -7/20 to get 5/8. So we will add that is sum up x and - 7/20, which is equal to 5/8. Thus, forming an adequate equation and doing the required calculations, we can easily calculate the value of x i.e, the required number.

In these type of questions, the final answer is just given in the question Itself. By understanding the question carefully but can do the step required and get our final answer.

Let's find out...

Let the required number be x.

According to the problem,

• - 7//20 + x = 5/8
• (-7 + 20x)/20 = 5/8
• - 7 + 20x = 5/8 × 20
• - 7 + 20x = 100/8
• - 7 + 20x = 50/4
• - 7 + 20x = 25/2
• 20x = 25/2 + 7
• 20x = (25 + 14)/2
• 20x = 39/2
• x = 39/2 ÷ 20
• x = 39/2 × 1/20
• x = 39/40
