Question

The sum of half number and 49 is 9/4 of the number. Find the number

Answer 1

Answer:

Let the unknown number be X.

0.5X+49=2.25X

2.25X = 0.5X + 49

2.25X - 0.5X = 49

1.75X = 49

X= 49÷1.75

X=28

The end

Answer 2

Answer:

187/2

Step-by-step explanation:

Let the number be x

half of x is x/2

x/2 + 49 = 9/4

(x + 98)/2 = 9/4

x + 98 = 9/2

2x + 196 = 9

2x = 9-196

2x = 187

x = 187/2
