Lisa has 12 more stickers than John, and together they have 60 stickers. What is the ratio of the number of Lisa’s stickers to t

Harman [31]

Answer:

The ratio of the number of Lisa’s stickers to the number of John’s stickers is 3/2

Step-by-step explanation:

Step 1

Let

x ----> the number of stickers that Lisa has

y ----> the number of stickers that John has

we know that

$x+y=60$ ------> equation A

$x=y+12$ ----> equation B

Solve the system by substitution

Substitute equation B in equation A and solve for y

$(y+12)+y=60\\ 2y=60-12\\ 2y=48\\ y=24$

Find the value of x

$x=y+12$ -----> $x=24+12=36$

therefore

Lisa has 36 stickers and John has 24 stickers

Step 2

Find the ratio of the number of Lisa’s stickers to the number of John’s stickers

x/y

substitute

$\frac{36}{24}=\frac{3}{2}$
