Answer:
1. 18:1
2. 125
3. 27
Explanation:
Question 1:
Car = 9 feet
Model = 6 inches
We will have to make both the units the same so that we can calculate the ratio.
Car = 9 x 12 = 108 inches
Model = 6 inches
Ratio of car to the model;
108 : 6
= 108 / 6
= 18/1
= 18:1
Question 2:
Total bricks = 175
Red bricks = 5
Total red and grey bricks = 5+2 = 7
175 x 5/7
= 125
Question 3:
Total = 117
Onion = 3
Total ingredients = 1+3+9 = 13
117 x 3/13
= 27
Hope this helps!
