Converting and Calculating Ratios

To express the given quantities in the same units and calculate the ratios, we can follow these steps:

1. Converting 600 grams to kilograms: - To convert grams to kilograms, we divide by 1000 since 1 kilogram is equal to 1000 grams. - Therefore, 600 grams is equal to 0.6 kilograms.

2. Calculating the ratio: - The ratio of 600 grams to 2 kilograms can be calculated by dividing 600 grams by 2 kilograms. - This gives us a ratio of 0.6 kilograms to 2 kilograms, which simplifies to 0.6:2 or 3:10.

Problem Solving with Ratios

Now, let's solve the problem by creating the ratio for the given scenario:

Problem: In a class of 35 students, 7 students play basketball. We need to find the part of the class that plays basketball.

Solution: - We can create the ratio of the number of students playing basketball to the total number of students in the class. - The ratio is 7 students (playing basketball) to 35 students (total in the class). - This simplifies to 1:5.

Therefore, 1/5 of the students in the class play basketball.
