Question

Last week, the ratio of laptops to desktops sold at a computer store was 2:3. Eighteen desktop models were sold. How many laptop models were sold?

Answer 1

2/3 = x/13

Answer 2

*18

Answer 3

l : d = 2:3
\[\frac{l}{d}=\frac{2}{3}\]
let the common parameter be x.
\[l=2x\]
\[d=3x\]
it is given that l+d=18
so, 2x+3x=18

find x.
then find l(=2x)

Answer 4

sorry

Answer 5

it is given d=3x=18
therefore , x=6

therefore, l=2x=12
