Question

0.25×4f-0.25×3=0.05×10f-0.05×9​

Answer 1

Answer:

f = 3/5

Step-by-step explanation:

0.25*4f-0.25*3=0.05*10f-0.05*9

f-0.75=0.5f-0.45

0.5f=0.3

5f=3

f=3/5

Answer 2

Answer:

f=0.6

Step-by-step explanation:

$0.25 \times 4f - 3 \times 0.25 = 10f \times 0.05 - 9 \times 0.05$

$= > 1f - 0.75 = 0.5f - 0.45$

$= > f - 0.5f = - 0.45 + 0.75$

$= > 0.5f = 0.30$

$therefore \: f = 0.6$
