Answer:
a. 60 boys
b. 228 total students
Step-by-step explanation:
a. If there are 45 girls and the ratio of girls to boys is 3:4, then there are 60 boys. The common multiple is 15.
3 * 15 = 45
4 * 15 = 60
45:60 = 3:4
——————————
b. First we need to find out how many boys there are.
95 / 5 = 19
19 * 7 = 133
So, there are 133 boys and the given number of girls is 95. To find out how many total students there are, we need to add 133 and 95.
133 + 95 = 228
Find the volume of each and then divide the volume of the box by the volume of the cube.
Volume of box: 8 1/2 x 5 1/2 x 2 1/2 = 116 7/8 cubic inches.
Volume of cube = 1/2^3 = 1/8 cubic inches
Number of cubes: 116 7/8 / 1/8 = 935 cubes.
It is proportional because all the sides are equal.
