To find three equivalent ratios to the given ratio of boys to girls (20/15), we need to multiply both the numerator and denominator of the ratio by the same number. Here's how you can do it step by step:
Step 1: Identify the current ratio:
The current ratio is boys to girls, given as 20/15.
Step 2: Find a common multiple:
To find an equivalent ratio, we need to multiply both sides of the ratio by the same number. Find a common multiple of 20 and 15, which is 60.
Step 3: Multiply the ratio by the common multiple:
Multiply both the numerator and the denominator of the ratio by 60:
20 * 60 / 15 * 60 = 1200/900
Step 4: Simplify the equivalent ratios:
To simplify ratios, we can divide both the numerator and denominator by their greatest common divisor (GCD). In this case, the GCD of 1200 and 900 is 300.
1200/900 รท 300/300 = 4/3
So, the three equivalent ratios to the original ratio of boys to girls (20/15) are:
1. 1200/900
2. 4/3
3. 4:3
Yes. You are right! :-)
Do it the same way I showed you earlier.
