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
[tex]x+y=60[/tex] ------> equation A
[tex]x=y+12[/tex] ----> equation B
Solve the system by substitution
Substitute equation B in equation A and solve for y
[tex](y+12)+y=60\\ 2y=60-12\\ 2y=48\\ y=24[/tex]
Find the value of x
[tex]x=y+12[/tex] -----> [tex]x=24+12=36[/tex]
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
so
x/y
substitute
[tex]\frac{36}{24}=\frac{3}{2}[/tex]
