Question

0.25(4f-3)=0.05(10f-9)​

Answer 1

1f - 0.75 = 0.5f-0.45

1f - 0.5f = -0.45+0.75

0.5f = 0.30

f =0.30/0.5

f = 0.6

Answer 2

Answer:3/5

Step-by-step explanation:

0.25(4f-3)=0.05(10f-9)​

(1/4)(4f-3)=(1/20)(10f-9)

f-3/4=f/2  -9/20

f/2=3/4   -   9/20

f=3/2   -   9/10

f=(15-9)/10

f=6/10

f=3/5
