Three fifths of the 60 vehicles were trucks. How many trucks were there?

One way to look at this problem: Since the ratio of cars to trucks is 7:3, ... How many groups of 10 are there? Since there are 60 vehicles, 60 / 10 = 6 ---> there are 6 groups of 10. Since there are 7 cars in each of the 6 groups: 6 x 7 = 42 cars. Since there are 3 cars in each of the 6 groups: 6 x 3 = 18 trucks.

Step-by-step explanation:

is it right

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.

answer: 72: 111
