Answer:
<em>The ratio of the diameter of ball A to the diameter of ball B is 10:19.</em>
Step-by-step explanation:
<u>Ratios</u>
A ratio is a relation between two quantities and it's calculated as a division. For example, the ratio between 8 and 4 is 8:4 = 8 / 4 = 2.
We are given the diameters of two balls as follows:
The diameter of the ball A=30mm
The diameter of the ball B=5.7 cm = 57 mm
The ratio of the diameter of ball A to the diameter of ball B is 30:57. Dividing both numbers by 3, we have: ratio=10:19
The ratio of the diameter of ball A to the diameter of ball B is 10:19.
Answer:
fifth graders= 93 shirts
sixth graders= 156 shirts
teachers= 51 shirts
Step-by-step explanation:
31% of 300 is 93
