Question

If 0.25 (4f-3) = 0.05 (10f-9), then f is equal to :

(a) 0.6 (b) 0.8 (c) 0.5 (d) 0.4​

Answer 1

ANSWER

0.6

Step-by-step explanation:

0.25 can be written as 25/100 also 0.05 can be written as 5/100

now 25/100(4f-3)=5/100(10f-9)

100 on both sides cancels and 5 will cancel 25 with 5 remaining is

5(4f-3)=(10f-9) multiple

20f-15=10f-9

take the like terms one side

20f-10f=-9+15

10f=6

f=6/10

f=0.6
