7/8 = x/48
Perform cross multiplication:
a/b = c/d
ad = bc
a = 7 ; b = 8 ; c = x ; d = 48
7*48 = 8x
336 = 8x
336/8 = x
42 = x
7/8 = 42/48
42 ÷ 6 = 7
48 ÷ 6 = 8
Answer:
5 laps
Step-by-step explanation:
We can use ratios to solve
3 minutes 15 minutes
----------------- = ------------------------
1 lap x laps
Using cross products
3x = 15
Divide each side by 3
3x/3 = 15/3
x = 5
He can do 5 laps
