Express the following quantities as a ratio. 1. 18hrs to 2days.
2. 3kg to 500g
3. 48secs to 5mins.
4. 4days to 2weeks
5. 2mm to 100cm​

pls show working

1.

convert the days to hours

divide both sides by the smallest no. i.e

18:48

18/18:48/18

1:2

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4

step-by-step explanation:

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
